God cautions His people to understand that worshiping God, both giving and serving, must come from a heart that is pure and devoted to Him, not just outward religious activity. God cares more about the attitude of our hearts than the amount of our giving. He cares more about our motive than our money. He desires that we worship with a right heart. In Haggai 2:10-17, God told the prophet Haggai to help the Israelites to understand that what really matters to God is that they worship Him with a right heart.
