Giving is scriptural
The Bible says we should; "Bring all the tithes into the storehouse so there will be enough food in my Temple. If you do,” says the LORD of Heaven’s Armies, “I will open the windows of heaven for you. I will pour out a blessing so great you won’t have enough room to take it in! Try it! Put me to the test!" Malachi 3:10 (NLT)
Generous giving is an acknowledgment that everything we have is a gift from God, and is to be used in His service; (Luke 12:33, Acts 20:35, 1 Timothy 6:17-19, James 1:17, 1:27, 1 Peter 4:10).
The Bible teaches us to use whatever talents, abilities and wealth God has entrusted to us for His service. We have different gifts, according to the grace given to each of us. If a man's gift is prophesying, let him use it in proportion to his faith. If it is serving, let him serve; if it is teaching, let him teach; if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully. (NIV, Romans 12:6-8)
Giving should be done cheerfully and with gratitude, rather than as an obligation (2 Corinthians 9:6-7), and not for the purpose of public recognition. (Matthew 6:1-4).
