I have heard of God, Jesus, the Holy Spirit, and the Bible.

I knew you only by hearing, but now my eyes see you. "(Job 42.5)

Many, many more people have even heard about Christianity, the teachings of the bible. But, they have not yet been taught by God Himself, the Holy Spirit and Jesus.
Who is responsible to prove his existence is God himself, because he wants people to receive faith, knowledge, the certainty that he is real.
Many preachers of the word of God say that they have no religion, when in fact, they have a yes, because religion is to reconnect with God, or through the bible, of small talk, or through nature, of drugs, or through Means and good works, or by means of offerings in the woods, in waterfalls, crossroads, through sacrifices of animals, of money, of Philosophy, of own concepts, etc., and through faith.
What is the right religion, how should I reel myself with God?
The Bible says they will all be taught by God Himself.
It is written in the Prophets, 'And they shall all be taught of God.' Therefore, everyone who hears the Father and learns from him comes to me. John 6:45.
Everyone has the opportunity to hear the voice of God, that voice has faith, has knowledge about the kingdom of heaven, about Jesus, about the Holy Spirit.
God teaches all that Jesus has done for us, has learned, and what belongs to us, our inheritance, rights and duties, what we can assume in our prayers and live.
Jô had a good character and respected what he heard about God at the time. Until God taught him personally through the Holy Spirit.
I can be evangelical, Buddhist, Catholic, Spiritist, Muslim, candomblé, left, right, Christian of various denominational lines, but as long as I do not learn from the Holy Spirit, my religion is still without connection with the world of Faith, of the experience with God himself.
Faith reveals the ethics of God's kingdom, its character, will, how we should truly follow it, without deceit, cheating, obscure interests, etc.

God bless us with our faith in Jesus.
