How do we know that God does not need our contributions?

God's self-sufficiency and sovereignty are foundational doctrines in Reformed theology. In Psalm 50:10-12, God declares that He owns the cattle on a thousand hills, emphasizing that He does not need our sacrifices because He created everything. The reality is that our contributions are not for God's benefit, but rather for our growth and participation in His divine economy. When we give, it should stem from a heart transformed by grace, recognizing that we are merely stewards of what belongs to Him. God does not seek gifts out of need; instead, He desires our hearts as a response to the grace He has freely given us in Christ. Understanding this helps us approach our service and contributions with the right motives and an attitude of worship, rather than obligation.
