What does the Bible say about giving to God?

In Isaiah 43:24, God expresses disappointment over the lack of offerings from Israel, symbolizing a coldness of heart towards worship and gratitude. This reminds believers that our giving reflects our relationship with God. Those who possess wealth must remember their responsibilities to give adequately, while those with little should still give with a heart of faith. Biblical giving is not merely about the monetary value but about the attitude behind the gift; even the smallest offering, given sincerely, is precious to God.
