“Beloved, if our heart does not condemn us, we have confidence before God” (1 John 3:21).
The confidence of which John writes points to a kind of openness; that there is nothing to hide before God. Because I know He knows me; that He is not blind to my sin, struggles, and shortcomings, I can openly, transparently, confessionally, and confidently set them all before Him. This confidence is rooted in the atoning work of Jesus Christ; a confidence that refuses to allow Satan to steal away the joy of salvation with the poisoned memories of the past for which Christ died. It is a confidence that lives forward into the promises of God.
