Killing Sin Does Not Make You New
"If we boil the Christian life down to simply killing sin, we rob ourselves of the deepest hope and highest joys.
Yes, every true Christian will be killing sin. Any other version or distortion of Christianity falls short of what Christ died for. “Put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires” (Ephesians 4:22). “If you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live” (Romans 8:13). If we do not kill sin, we will die in our sin. But if we wage war against our sin, in the power of the Spirit, we prove that Christ is alive in us, and that we will never die.
Killing sin is essential to the Christian life, but it’s not the essence of the Christian life. When Christ calls us to deny ourselves, take up our cross daily, and follow him — and he does summon us to deny ourselves — he does so that we “may have life and have it abundantly” (John 10:10). What we put on is far greater than anything we put off or leave behind.." from the article: Killing Sin Does Not Make You New
