What is the relationship between law and grace?
“The law was given through Moses; grace and truth came through Jesus Christ” (John 1:17)
When Christ “became flesh and dwelt among us” (John 1:14), He was full of grace and truth. But what does this mean, and what is the relationship between these and the law that was given through Moses?
To give a correct answer we must remember that in the beginning, God dwelt with his people (Adam and Eve) in the Garden of Eden. Then, as a consequence of sin, man could no longer dwell in God’s holy presence. But in His grace, He created a way to dwell with His people (Israel) in a tabernacle and later in a temple. In the context of the construction of the tabernacle, Moses asked God to see His glory (Exodus 33:18). In response, God did not show Himself physically to Moses, but revealed Himself as “The Lord, the Lord, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness…” (Exodus 34:6).
The phrase “abounding in steadfast love and faithfulness” can also be translated “rich in grace and truth”. This describes God’s faithfulness to the old covenant, to the covenant of the law, which He had made with Israel and which had Moses as mediator. Therefore, most certainly, when John describes Jesus as being “full of grace and truth” (John 1:14), this goes back to Exodus 34:6 to affirm that God’s faithfulness found its ultimate expression in the incarnation of his Son, in his new covenant, a covenant of grace.
What John wants to show is a progressive and superior development of the new covenant over the old covenant, a superiority of grace over the law. The apostle shows us this superiority, personifying it in John the Baptist, Moses and Jesus Christ (Luke 16:16).
