How you handle your money has a lot to do with the condition of your heart, and it also has an impact on what God can and will do in and through your life. Living generously is something we learn, just as we learn to pray and to trust God. If we will learn to live our lives oriented to Him, He will pour out blessings beyond anything we could ever imagine.
God gave us His best, and the whole Jesus-story is an expression of the value God attaches to you and me. How we use our time, our talents, and our resources is a reflection of what we value. When we see God, we will want Him to see that we value Him and have been generous with Him in every part of our lives.
