What is the message of king David's crime?

Answer 1

The episode in David's life serves as an encouragement to all who have fallen into serious sin. By confessing our sin and showing sincere repentance, we can regain our most precious possession, our relationship with God. The momentary pain and shame we may have to endure is far better than the anguish caused by remaining silent, or the dire consequence of allowing ourselves to become hardened in a rebellious course. (Psalm 32:9) Rather, we can experience the warm forgiveness of a loving, merciful God, "the Father of tender mercies and the God of all comfort." (2 Corinthians 1:3)

Answer 2

King David's misstep teaches us 1) Even the most righteous person cannot think that a transgression will be ignored.

2) The efficacy of repentance.

Note:

David appeared to commit adultery but was not technically culpable, since the cuckolded man was a rebel who deserved to die, was sentenced to die, and had actually divorced his wife with whom David slept (Talmud, Shabbat 56a).Nonetheless, the circumstances were considered a blemish in David's otherwise perfect record of righteousness, and God punished him by taking the life of one of his sons; and two other sons (Absalom and Adonijah) rebelled against David's rule and ended up killed.
