King Saul disobeyed God while David was, by and large, obedient. King Saul was jealous of David because David's way was more successful (1, 2 Sam). Now and then, however, David too followed his self-will and could sin greatly. When this happened he would quickly return to God and begin anew to fulfill what God had in mind for David and David's people.
There is a great difference between those who persist in doing what they please and those who repent and once more seek God's will for them. From David's example it is clear that God will forgive lapses in those who turn to him. This is encouraging for us who intend to be faithful but sometimes fail to live up to our intentions. Our cause is not hopeless. We have reason to worry only when we are not honest with God or ourselves. The remedy is within our reach, namely, deciding to let go of dishonesty.
Lord, sometimes I think that I move between the attitudes of Saul and David. When I lapse into dishonesty correct me as you did David. Save me from becoming like Saul and destroying myself.
