What does the Bible say about offerings to God?

In 2 Samuel 24, King David emphasizes that he will not offer to God something that costs him nothing. This principle underscores the importance of sacrificial giving in worship. God desires offerings that come from a heart willing to sacrifice, just as the widow in Mark 12 gave all she had, which was notably more significant than the larger gifts of the wealthy who gave from their abundance. Such offerings reflect our recognition of God’s grace and mercy towards us, as they demonstrate our commitment and love.
