You and I are in the middle of a war. We fight a fierce enemy each and every day. Each morning this enemy renews its relentless assault, sometimes quietly, sometimes boldly but always in opposition to what is right and good. That enemy is sin. Whether you realize it or not, sin daily wages war against our soul (1 Peter 2:11). To stand idly by as if nothing is going on is to have lost the battle. Sin will overcome us unless we consciously fight back. That is why the apostle Paul wrote:
“For 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, ESV)
Life lived according to the whims of our sinful nature brings about a life of death. But for those who have trusted in Christ and have the indwelling Holy Spirit, life can be different. Prior to salvation, the Bible teaches that we were enslaved to sin (Rom. 6:6) and following our own sinful lusts and passions (Ephesians 2:1-3). But once we are made new by the shed blood of Christ, everything changes. We are slaves to sin no more. We are no longer powerless against the onslaught of sin's deceit.
