The phrase “great grace” is used only once in the Bible: Acts 4:33 And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all. The Bible speaks often of grace, but we notice here that for great grace to be used is a very special thing. The word grace is used 122 times in the New Testament and 37 times in the Old Testament, so that wonderful word is used a total of 159 times in the Bible. That is an average of 2 1/2 times for each book of the Bible.
Grace is a wonderful word, because it expresses a work that God does for us that we cannot do for ourselves. To express great grace in our language, we use words such as amazing and wonderful. Some very precious songs have been written with grace in mind: Amazing Grace, Wonderful Grace of Jesus, and Grace Greater Than All Our Sin, et al.
How to express this great grace is actually impossible for humans to accomplish. Grace is a mystery, and we are the recipients of it by God’s own will. How wonderful it is that God would extend his grace to us! We are undeserving of any grace from God, but he saved us by his grace. Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: I would call this Great Grace.
