In John 1:17, John writes, “the law was given through Moses; grace and truth came through Jesus Christ.”
Tied to Moses, the exodus and the giving of the law, God revealed himself to Israel. He revealed himself with a new name: Yahweh. He revealed his power through salvation. He dwelt among the people. They saw a form of the glory of the Lord at the tabernacle.
But in Jesus, God’s revelation is greater. The salvation be brings is greater. His dwelling as ‘the Word become flesh’ is greater. His glory is greater. The new covenant is greater than the old covenant. The theme of the new being better than the old is only in embryonic form John 1. He unpacks it as the narrative unfolds.
Check out this thread of coherence:
John 2: The good wine is kept until the end (John 2:10). What comes later supersedes what came earlier. The new covenant is greater than the old.
John 3: Jesus rebukes Nicodemus for not understanding these things (John 3:10). What things? That you “must be born of the water and the Spirit” (John 3:5). What’s that all about? Jesus interacts with Ezekiel. In Ezekiel 36, he prophecies of the new covenant. God says, “I will give you a new heart, and a new spirit I will put within you . . . and I will put my Spirit within you” (36:26-27). The new covenant is greater than the old.
John 4: The Samaritan woman said to Jesus, “‘you say that Jerusalem is the place where people ought to worship.’ Jesus said to her, ‘Woman, the hour is coming when neither on this mountain nor in Jerusalem will you worship the Father'” (John 4:20-21). The time is coming when worship will be decentralized. No more adherence to Deuteronomy 12. Jesus fulfills the place of worship. He is the meeting point between God and man. So, as my dear friend Julian Freeman once said, “Worship is re-centralized.” Yes, re-centralized in Jesus. The new covenant is greater than the old.
