The Bible says that our core problem, the fundamental reason we do what we do, is sin. What is being said here? Scripture is defining sin as a condition that results in behavior. We all are sinners, and because of this, we all do sinful things. This is why I said that our core problem precedes our experience. David captures it well in Psalm 51: Surely I was sinful at birth, sinful from the time my mother conceived me” (v.5). Tripp, Instruments in the Redeemer’s Hands, p. 10.
