We consider it a privilege to give back to God what He has so freely given to us. We praise God for His goodness and the work He does through our consistent sacrificial giving. 

What God says about tithes and offerings?

Malachi 3:10-11 Amplified Bible (AMP)

10 Bring all the tithes (the whole tenth of your income) into the storehouse, that there may be food in My house, and prove Me now by it, says the Lord of hosts, if I will not open the windows of heaven for you and pour you out a blessing, that there shall not be room enough to receive it.

11 And I will rebuke the devourer [insects and plagues] for your sakes and he shall not destroy the fruits of your ground, neither shall your vine drop its fruit before the time in the field, says the Lord of hosts.

2 Corinthians 9:7 English Standard Version (ESV)

Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver.

Proverbs 3:9 New International Version (NIV)
Honor the Lord with your wealth, with the firstfruits of all your crops;

Luke 6:38New International Version  (NIV)

38 Give, and it will be given to you. A good measure, pressed down, shaken together and running over, will be poured into your lap. For with the measure you use, it will be measured to you.”
