Well, the question of how many years as a renewed christian will never be the basis of how a person change but how he accept Christ in Him. I may have been in in and out of His divine way but still here I am to serve.
Since the birth of the universe and of the earth, God have always been there for He made the heavens and all the ones down here on earth. We owe Him everything we have including our very life.
This is our way of saying Thank You to Him. For the breath of life, for our families who keep supporting our us, for our community, for the friends we met and cherish, fr our special someone, for the promise of salvation and also for the most important person who touches our lives, Christ Jesus.
It is easy to be called a Christian, but being in Christ isn't. Just remember that there is a God who loves you most and for His unfailling love, He sent you a brother and a freind just to die for your crimes, your sins.
