Being born again is an event that takes place in every true Christian’s life at some point. You “put off” your previous way of living and thinking, living according to the lust to sin in your flesh. You are born anew into a life with Christ; you become a new creation that is Spiritual and eternal. “Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.” 2 Corinthians 5:17. After you are born again you see the kingdom of God as your goal and everything outside of that becomes rubbish to you. Read about Paul’s spiritual rebirth in Philippians 3:4-10.
