God makes himself known to the world, and he certainly makes clear his will for the world -- for the world to trust him:
Jesus said to them, 'I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. But I said to you that you have seen me and yet do not believe. All that the Father gives me will come to me, and whoever comes to me I will never cast out. For I have come down from heaven, not to do my own will but the will of him who sent me. And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day'.' - John 6:35–40
God reveals, draws, and transforms humanity to trust him. He makes known what all of us are to be -- humble and transformed to love what he loves. When we are humbled before him, we are then receptive. He works outside of us, beyond us, in spite of us, and within us to his end by his beginning and means. Many might twist, lie, deceive, or merely ignorant of him and how he works, but that does not take away him, how he works, and the truth and love in which he works by to make and work in humble hearts. Jesus explains it through a parable and analogy of soil and seeds:
“Again he [Jesus] began to teach beside the sea. And a very large crowd gathered about him, so that he got into a boat and sat in it on the sea, and the whole crowd was beside the sea on the land. And he was teaching them many things in parables, and in his teaching he said to them: 'Listen! Behold, a sower went out to sow. And as he sowed, some seed fell along the path, and the birds came and devoured it. Other seed fell on rocky ground, where it did not have much soil, and immediately it sprang up, since it had no depth of soil. And when the sun rose, it was scorched, and since it had no root, it withered away. Other seed fell among thorns, and the thorns grew up and choked it, and it yielded no grain. And other seeds fell into good soil and produced grain, growing up and increasing and yielding thirtyfold and sixtyfold and a hundredfold.' And he said, 'He who has ears to hear, let him hear.'
And when he was alone, those around him with the twelve asked him about the parables. And he said to them, 'To you has been given the secret of the kingdom of God, but for those outside everything is in parables, so that 'they may indeed see but not perceive, and may indeed hear but not understand, lest they should turn and be forgiven'.’
And he said to them, 'Do you not understand this parable? How then will you understand all the parables? The sower sows the word. And these are the ones along the path, where the word is sown: when they hear, Satan immediately comes and takes away the word that is sown in them. And these are the ones sown on rocky ground: the ones who, when they hear the word, immediately receive it with joy. And they have no root in themselves, but endure for a while; then, when tribulation or persecution arises on account of the word, immediately they fall away. And others are the ones sown among thorns. They are those who hear the word, but the cares of the world and the deceitfulness of riches and the desires for other things enter in and choke the word, and it proves unfruitful. But those that were sown on the good soil are the ones who hear the word and accept it and bear fruit, thirtyfold and sixtyfold and a hundredfold.' And he said to them, 'Is a lamp brought in to be put under a basket, or under a bed, and not on a stand? For nothing is hidden except to be made manifest; nor is anything secret except to come to light.If anyone has ears to hear, let him hear.' And he said to them, 'Pay attention to what you hear: with the measure you use, it will be measured to you, and still more will be added to you. For to the one who has, more will be given, and from the one who has not, even what he has will be taken away'.' - Mark 4:1–25
And those who have come to believe in him, also then love him because he first loved, therefore we are transformed to live 'beloved' by him in this life and discern what is not truthful or loving:
'Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already. Little children, you are from God and have overcome them, for he who is in you is greater than he who is in the world. They are from the world; therefore they speak from the world, and the world listens to them. We are from God. Whoever knows God listens to us; whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of error.
Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. Anyone who does not love does not know God, because God is love. In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. Beloved, if God so loved us, we also ought to love one another. No one has ever seen God; if we love one another, God abides in us and his love is perfected in us.
By this we know that we abide in him and he in us, because he has given us of his Spirit. And we have seen and testify that the Father has sent his Son to be the Savior of the world. Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. So we have come to know and to believe the love that God has for us. God is love, and whoever abides in love abides in God, and God abides in him. By this is love perfected with us, so that we may have confidence for the day of judgment, because as he is so also are we in this world. There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love. We love because he first loved us.If anyone says, 'I love God,' and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen. And this commandment we have from him: whoever loves God must also love his brother.' 1 John 4:1–21
Even from the beginning of the Bible, God called his people Israel to love him which would then be recognized among the world to proclaim to all nations the truth and love of God:
You shall love the Lord your God with all your heart and with all your soul and with all your might.' - Deuteronomy 6:5
Declare his glory among the nations, his marvelous works among all the peoples! - Psalms 96:3
Jesus repeated and confirmed this in his answer to a lawyer:
But when the Pharisees heard that he had silenced the Sadducees, they gathered together. And one of them, a lawyer, asked him a question to test him. 'Teacher, which is the great commandment in the Law?' And he said to him, 'You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: 'You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets'.' - Matthew 22:34–40
We are not called to love ourselves but to love him and others. We love others how we'd want to be treated, and if we primarily want what God wants, then we truly love our neighbor as we would care for our very own lives. God ensures that through Christ no one is condemned or separated, making his promises truthful and loving (i.e. trustworthy):
There is therefore now no condemnation for those who are in Christ Jesus ... nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord. - Romans 8:1 & 39
Some fear being left to confusion, evil, and suffering in this life, but he truly guides, and primarily guides the heart regardless of what one may experience or originally believed:
May the Lord direct your hearts to the love of God and to the steadfastness of Christ. - 2 Thessalonians 3:5
We are transformed to live a holy life, which means distinct or different from the world, because of him and his will is at work in hearts. It's not merely the lifestyle that's different but the God we are transformed by and follow that is different:
But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy. - 1 Peter 2:9–10
So flee youthful passions and pursue righteousness, faith, love, and peace, along with those who call on the Lord from a pure heart. - 2 Timothy 2:22
And you were dead in the trespasses and sin sin which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience—among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.' - Ephesians 2:1–10
This is why Jesus trained his disciples to trust him and pray to God for God's will to be effective in them as they live for him:
And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him. Pray then like this: 'Our Father in heaven, hallowed be your name. Your kingdom come, your will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from evil. For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses.' And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you. Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also. - Matthew 6:7–21
Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. - 2 Corinthians 5:17
Therefore, we become a people transformed to follow him regardless of our experience or life because he's more valuable and worthy than life itself. We trust what he says (truth) and love what he loves (him and others). It's not about who we are but rather who he is -- at work in us to do his will.
