Today's devotion from Psalms 50 & 51.
God does not need you.
Let that sink in for a moment. He is not contractually forced to accept your offerings or, in the days before Christ, your sacrifices. There is not cosmic law that overrules Him, forcing Him to act or abide in certain and specific ways. He. Is. God. He prescribed offerings. He chose to accept them. He decided of His own volition to associate with fallen man, but on His terms.
In Psalm 50, we are reminded of this fact. God is not obligated to love us, accept us, or forgive us. Therefore, He chastens those who would treat His worship as if it were merely a hoop through which to jump, or a box that needed checking. There is something God desires more than legalistic obedience.
Further, He challenges those with the audacity to, "recite my statutes, or take my covenant on your lips" in an insincere manner. These who are so twisted and mangled that they could get away with simply going through the motions of worship are rebuked by God by His accusation.
What is it that God wants? If its not mere obedience, then what?
When offerings are made with "a sacrifice of thanksgiving", then God will deliver in the day of trouble. He states, "The one who offers thanksgiving as his sacrifice glorifies me; to one who orders his way rightly I will sho the salvation of God!" (Psalm 50:23, ESV)
The truth of this psalm is given to, "you who forget God." How do they forget God? They were going through the motions of worship. We can "worship" without remembering God. Today, God is not just wanting your begrudged obedience, rote actions, or your dispassionate allegiance. He desires your heart. Yet, the heart given to Him will produce a genuine obedience to Him.
