Aren't you (if you know the Lord Jesus as your Savior) glad that there is forgiveness with God?
When we were first saved our Pastor Gibbs had us learn a "chorus of the month". This is one of them.
It's a blessing that each passing year the believer recognizes this more deeply. We serve a wonderful God; We have an "unspeakable gift". These spiritual blessings are sometimes difficult to put into words, but we are supposed to praise Him always. I have nothing to boast in except this wonderful Lord!
