Giving is a demonstration of our love for God and our loyalty to God’s family, the local church. Everything we own we have received from God. We return to him the first ten percent (the firstfruits or the tithe) of our income, because Malachi 3:10 shows us that it belongs in the storehouse, the local church, which is the place where our families receive spiritual nourishment and where are equipped for our ministry in the world around us.
The other 90% God gives to us to steward well. From that money we pay our bills, we save up for later, and we are generous whenever the Lord stirs our heart. When this is how we handle our finances, Malachi teaches us that we will blessed accordingly.
