Honor the Lord with your wealth, with the firstfruits of all your crops; then your barns will be filled to overflowing, and your vats will brim over with new wine.
~ Proverbs 3: 9-10
Be careful not to confuse God's view of wealth with your view of money. God doesn't need anything you have - God desires for your heart to be locked onto Him.
That catch? When our heart begins to beat like God's heart, the things we want -- changes. We begin to want for others to win, for the hungry to be fed, for the lost to be found, for the lonely to be loved.
Want to develop a giver's heart? Flip the script. Focus on the things which make you angry and unsettled. Those are the areas you care deeply about.
Seek out a way to be the light in those spaces. Use your talent, time, energy, and resources to solve that problem.
Give yourself first to serve... then you will be served beyond your expectations.
