Here are four great reasons...
GIVING INVOLVES YOU IN GOD'S MISSION
People often say, "God doesn't need money." That is very true, but God's mission does. Through His wisdom, God has given the task of reaching the world for Christ to the church. When you give, you are saying you believe that mission is important enough to fund.
GIVING CHANGES YOUR HEART
"...For where your treasure is, there will your heart be also." (Luke 12:34)
This means that our heart follows the things we value most. When we devote our finances to God's kingdom, we naturally become more passionate about what God is doing in our world.
GIVING INVITES GOD INTO YOUR FINANCES
Giving to His mission is how we tell God, "I want to do finances your way."
That's why He promises:
Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the LORD of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need. (Malachi 3:10)
GIVING PUTS GOD FIRST
"...No servant can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.” (Luke 16:13)
The biggest competitor against God for our heart is money. There can only be one master of our heart. When we choose to give, we say, "God is first!"
