Giving our tithes and offerings reflects a grateful heart that wants to give back to God a portion of what He has given us; in reality, what is already His. This is our opportunity to show God that He is first in our lives. the Bible says, the purpose of tithing is to teach you always to put God first in your lives *Deuteronomy 14:23). Tithing is a reminder that God is the supplier of everything we have. It is also God's personal invitation to an outpouring of his blessing in your life.
Matthew 6:20-21 "Store up for yourselves treasures in heaven ... For where your treasure is, there your heart will be also."
God uses the tithe as an investment where everyone involved gets a return. If we are blessed beyond our needs it is not for the purpose of living more lavishly but to bless others. The church and the kingdom are blessed, and yet God's nature is to also bless the giver.
Malachi 3:10 "Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this, says the Lord Almighty, and see if I will not throw open the floodgates of heaven and pour out so much blessing that you will have room enough for it."
