Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
~ 2 Corinthians 9: 7
Money and Christianity tend to have a struggling relationship.
At the core, all movement of giving should begin from our heart. From there, the giver cheerfully directs his giving.
Many guys focus on working harder to produce more income so he can give to God in exchange for a blessing. Don't do that - God can't be bought.
Instead, Soak your efforts in prayer and when the time comes to serve the lives around you, it will effortlessly come through your heart and flow into your time, your talents, your gifts, and your money.
