When we give God back the tithe that is His to begin with, He blesses us abundantly spiritually and physically. Notice that God says He commands tithes so "that there may be food in My house" (Malachi 3:10). Tithes are primarily used to feed His people spiritually! If we support the work God is doing through His faithful ministers, He promises to bless us far above anything we could imagine (Ephesians 3:20-21)!
