If we try to prove to God that we love Him, it is a sure sign that we do not love Him.
We are loved by God because of His unfettered grace. Don’t put chains back on! We don’t prove our love to others. We simply love them and they recognize it or don’t. Either way, we love them. The same is true with God. He knows whether we love Him. If we have to prove it, it is more for our own satisfaction and justification of our own lives when it was Jesus who justified us through the cross.
