God owes us nothing. We owe Him everything.
Romans 11:35-36 Or who hath first given to him, and it shall be recompensed unto him again? For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.
Every dollar in our pockets is a gift from God. Every lung full of air is His blessing. Every heartbeat is His manifested grace---our home, car, family, job, intellect, and talents are gifts to us from God.
And what does God want in return? Nothing more than our love, which manifests itself in obedience to Him, that we honor Him by receiving His Son Jesus as our Savior.
When we do that, His real giving begins. No, God isn't in debt to us; it is we who are in debt to Him.
God is the center of His universe. Is He the center of yours? If you are giving Him the glory due His name He is.
