Union with God

Theosis (also called divinization, deification, or transforming union) was one of the most important of early  Christian doctrines, but it has become such well kept secret that it is nearly unknown to most contemporary laymen.  It means participating in and partaking of God's Divinity.It is likely to sound so alien to our ears that we might quickly dismiss it as heresy, rather than realize it tis the heart of the Christian calling.
Yet, from the first chapter of Genesis, to Christ the Word of God, through the apostles, to numerous saints, theologians, and Christian writers throughout the centuries today and today, the message is clear: God made us to be like Him, wants us to become like Him. From the second-century St. Ireneaus, to the twentieth century C. S. Lewis, some theologians have used the most shocking language to bring home how shocking this gift of God is: "becoming gods", or even "becoming God".

"My dear people, we are already the children of god but what we are to be in the future has not yet been revealed; all we know is, that when it is revealed , we shall be like Him because we shall see him as he really is>" 1 John 3:2.

Jesus answered: Is it not written in your Law: I said, you are gods? So the Law uses the word gods of those to whom the word of God was addressed, and scripture cannot be rejected. "John10:34-35

And when everything is subjected to Him, then the Son himself will be subject in turn to the One who subjected all things to Him, so that God may be in all. 1 Cor 15:28.

Now you together are Christ's body, but each of you is a different part of it. 1 Cor. 12:27

But to all who accept Him he gave power to become children of God, to all who believe in the name of Him who was born not out of human stock or urge of the flesh or will of man but of God Himself! John 1:12-13.
You should pray like this:Our Father Jesus in Matt 6:9

God created man in the image of himself, in the image of god he created him, male and female he created them Genesis 1:27

--the Spirit and our spirit bear witness that we are children of God. And if we are children we are heirs of God and co-heirs with Christ, sharing His sufferings so we may share His glory.

Becoming God does not mean we become all powerful, all knowing, or that we remember saying "let there be light". It really means becoming Christ, or becoming divine, that God's God-ness is experienced and known not as something outside and separate, but as part of our being. It means knowing God as Jesus knew the father , so likeJjesus, we are with Him, fully human and fully divine.
