The preaching of the gospel must include the doctrine of inability.
3 For when we were still without strength, in due time Christ died for the ungodly. Romans 5:3 NKJV
3 For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, 4 that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit. Romans 8:3-4 NKJV
