The New and Living Way
Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, by a new and living way which He consecrated for us. (Hebrews 10:19-20)
Here, life under the new covenant of grace is described as the “new and living way.” This could be contrasted with the “old and dying way” of attempting to live under the old covenant of law. The “newness” of grace is not really a matter of time sequence, because the grace of God actually precedes the law in man’s history with God. The “tree of life” in the garden of Eden was God’s provision of grace for Adam and Eve. The promises of God to Abraham (given hundreds of years before the law) depended upon the faithful grace of God, not the legal performance of Abraham.
