In this sermon Why Do We Still Eat The Forbidden Fruit, sacrifice is indeed commanded by God. But your sacrifice is sickening to Him if you do not FIRST have MERCY in your heart. If you're going to be mean-spirited to your family after you worship and praise God then you are a hypocrite. When you sacrifice and don't have MERCY in your heart, you're not connecting sacrifice with the inward reality that is supposed to be the reason you want to sacrifice. You are involving yourself with God, and everything about God is love and mercy. Therefore, show mercy yourself if you are going to involve yourself with the God of love and mercy!
