Jesus is God. He, the Father and Spirit are One God, three persons. In a sense they are the initial pluralism within monism. They are co-eternal. None were created.

Jesus is returning to Earth at the end of days yet one need be saved before that time. Incidentally there are three basic Christian interpretations of scripture concerning end times. Those are pre-tribulation, post-tribulation and a millennialism. There are other names for those opinions.

Some believe the tribulation occurred in the first century AD as Jesus said it would when Jerusalem was destroyed by the Romans with a million dead Jews. This age of the gentiles is when the kingdom of God is increasing in the numbers of the saved before the Lord returns. Pre-tribbers, like Muslim twelvers believe a tribulation and Armageddon is ahead.
