EVIDENCED to who exactly? God? He doesn't know He made us a new creation? Other believers? So our walk is a kinda report card to believers to prove to them we're saved? To the unsaved? Boy you better be careful with that one!! ONE occasion of too much drink, ONE lie, ONE fit of anger, etc... and you will get the "Aha!! you call yourself a Christian."
Evidence to myself? I am a child of the One true God, Born again. In One Hand God the Father holds me. In the other Jesus Christ. And the Holy Spirit has sealed me with His Presence unto the day of redemption! NO ONE CAN SNATCH ME FROM THOSE HANDS OR UNSEAL ME!
I DO NOT have to prove that I am a Child of God by my works, good or bad. I'm a Child of God by birth! If you have kids, tell me, are they your kids by how they obey and behave? Or are they your children because they were BORN your child?
Am I saying that a born again believer should walk in the flesh? OF COURSE NOT! Further, there are always consequences for sin. For the unsaved (eternally lost) AND the saved. My consequences range from liver disease or death by auto for drinking, STDs and possible divorce for sexual sin,etc.., to being an ineffective witness to the world in bringing the Gospel, to possible immediate PHYSICAL death, to finally a loss of eternal rewards.
STOP looking at yourself and others in judging walks! Keep your eyes on our beautiful, Blessed Savior!
