And it happened, as the ark of the covenant of the Lord came to the City of David, that Michal, Saul’s daughter, looked through a window and saw King David whirling and playing music; and she despised him in her heart. 1 Chro 15:29
Saul’s daughter Michal despised David in her heart when she saw him whirling and playing music. She judged him in her heart, with her own prejudices and opinions. Beware that even such feelings in the heart are known by God. 1 Sam 16: 7 reminds us “…for man looks at the outward appearance, but the Lord looks at the heart.” And He will judge such sins if not confessed and repented of, as He did Michal.
We can’t help, out of our sinful nature, to have our own vices, thoughts and feelings about certain matters. Some of these may be unhelpful as in the case of Michal. We ought to, out of our daily communion with God, bring such matters before Him, seek forgiveness if they are unhelpful and ask for appropriate thoughts that may please Him.
