Romans 7:17-18, Watch Out for the Flesh
The Apostle Paul identified the source of mischief in the believer’s life as the sin that is within him which he identified as his “flesh”. It entices him to sin. And he speaks of a conflict within him, a tug of war between the flesh and the new nature within him. The new nature was formed in him when he received Jesus Christ into his life. The Holy Spirit now indwells him. The flesh does not speak of his body. His body is not evil. In fact, the body is the temple of the Holy Spirit of God.
