Jesus told his disciples that he will return only once and that when he does, after a time of great tribulation, it will be visible to everyone and be followed by immediate and dire consequences for those unprepared and for those who were adversaries of God.
Often a lot of people do not know to differentiate between Christendom, Christianity, religiosity and even limit religiousness to Christians, forgetting that there are many other religious groups who have all sorts of worship.
Christianity is a love affair. Each person calling himself or herself a Christian should live a life of service to God and Jesus, by serving each other, putting the needs of others before our needs, showing to others the love Jesus gave us.
In people saying God knows everything and claiming that Jesus would be God, adversaries of God receive an easy gainsaying danger because they can see how Jesus not at all knew everything, or in case he knows everything than it is clear that Jesus would not have told the truth on more than one occasion and as such would be a liar. The God of Jesus has man given the own possibility to choose what to believe and what to do, therefore it is up to man to make the right choice and to believe in the Only One true God or in the god man has created for himself or to please himself.
People can be irreligious, delusional or belonging to lovers of agnosticism, ignosticism, ietsism, scepticism, pantheism, atheism, strong or positive atheism, implicit atheism, and apatheism.

Not many believers may considered wise or powerful according to human standards, or may not being 'well born' or from "blue blood". In the Scriptures may be found many words also from foolish men. Many wrong actions of men are notated in the bible so that people can learn from them.

The Bible show us The Being Who makes us able to be a being. The collection of 66 books focus on That Most High Being without Whom no being or existence is possible. The Words of God are there to mould or form each creature of God. By allowing that Word of God to form us we can become reconstituted or 'made anew' by the Former God.
We can look at the biblical authors as Witnesses for Jehovah God, the divine Creator of many universes, as people who were called to testify before humankind and in several occasions were even willing to give up their life for what they considered to be the truth.
We look at a visible or invisible God, Who is the Being Itself Which created heaven and earth and gave life into beings which got to be.
