Firstly, a Christian is a NEW CREATION. ‘’therefore if any man be in Christ, he is a new creation: old things are passed away; behold all things are become new.’’ To walk in the newness of life as the Bible declares is to understand that we have become new creatures with new kind of life. This life is not human. It is ZOE, The God kind of life.
We are not talking about a change, behaviour or refurbished character. We are talking about a brand new man who has never existed before. Paul says that in God (Galatians 6:15). (Ehesians 4:22-24). The new creation is a new man created in God’s divine nature of righteousness and holiness. They are his attributes. (2 Peter 1:4).
Secondly, a Christian becomes the son of God when he becomes born again. This time of a different father. Not the earthly father but the heavenly Father through his seed. ‘’Which is born not of blood, nor of the will of the flesh, nor of the will of man, but of God.’’ (John 1:13) behold, what manner of love the father hath bestowed upon us, that we should be called the SONS OF GOD’’ This is why we cry ‘’Abba Father,’’ John 1:13, Romans 8:16-17.
