Recently I was told that in order to be saved, one "must confess all known sin in your life and with a sincere and rent heart ask God for forgiveness and confess that He [Christ] is Lord as He claimed in the Bible."
An important correction must be made to this statement, which I am dismayed to believe is very common. Namely, one does not have to confess all known sin in order to be saved. The thief on the cross certainly did not. He simply owned his sinfulness, and with faith looked to Christ's power to forgive and provide entry into the Kingdom. It is not that one must name every sin in particular, or even all those he can think of, or this would leave him always wondering if he had confessed enough. It suffices simply to own that we are sinful to a degree that we are quite unacceptable to God by anything we could ever do; that we cannot atone for ourselves even by a reformed life. In this way we confess not the particular extent our sins (for who could know it?) but the extent of Christ's power to save.
While it may be greatly beneficial to humble ourselves with exhaustive confessions, such practices cannot replace faith alone as the sole requirement for salvation.
