2 Corinthians 5:17-18; "This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun! And all of this is a gift from God, who brought us back to himself through Christ. And God has given us this task of reconciling people to him"(NLT)
To be born again means putting away the old life and putting on a new one, it is in other words called repentance. Repentance in Christianity means a sincere turning away, in both the mind and heart, from self to God. It involves a change of mind that leads to action, the turning away from a sinful course to God.
If you truly repent of your sins and accept Christ as your Lord and Saviour then your mind has changed from the old to the new, you are born again and will be called a new creation and also an Ambassador for Christ.
A new creation is a transformed mind, that is why the bible says in Romans 12:2; "Don't copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God's will for you, which is good and pleasing and perfect."(NLT)
The transformation is in your mind, as a man thinks in his heart so is he! The transformed mind is the recreated mind, if you still think like the old man then you need transformation through God's word to become new. God's word is the key!
Heavenly Father, I thank you for making me a new creation. I am delivered, I am saved, I am a new creation in Christ Jesus. I am an ambassador for Christ. The word of God is dwelling in me richly, I am being transformed day by day to the glory of God. Hallelujah!
