The essential or basic sin is idolatry — putting something or even someone before or above God. David asks God to search him, to know his heart, to test him and recognize his concerns. Of course, God sees David’s offenses clearly. David expects God to not only see his idolatry, but also to lead him out of it and into the way of everlasting life. David sings:
23 Search me, God, and know my heart;
test me and know my concerns.
24 See if there is any offensive[idolatrous] way in me;
lead me in the everlasting way.
Jesus comes to earth to lead us out of death and into everlasting life. He comes so we may have life and have it abundantly.
