John Piper said this quote
“ What then do we learn from Paul's unbroken pattern of beginning and ending his letters this way (Grace be to you. Grace be with you.)? We learn that grace is an unmistakable priority in the Christian life. We learn that it is from God the Father and the Lord Jesus Christ, but that it can come through people. We learn that grace is ready to flow to us every time we take up the inspired Scriptures to read them. And we learn that grace will abide with us when we lay the Bible down and go about our daily living. In other words, we learn that grace is not merely a past reality but a future one. Every time I reach for the Bible, God's grace is a reality that will flow to me. Every time I put the Bible down and go about my business, God's grace will go with me. This is what I mean by future grace. ”
