Christians speak often of the “New Covenant,” but many view it through the lens of replacement theology and supercessionism. Doing so completely disconnects the New Covenant inaugurated in Yeshua HaMaschiach (Jesus the Christ), Who is both priest and king of His people, from the covenants (sealed contracts) God made with His people through Abraham, Isaac, Jacob and even Moses.
Without an understanding of those covenants, the New Covenant has no real meaning. The why behind these contracts is at the heart of the Torah reading כי תשא Ki Tisa (“when you take”; Exodus 30:11–34:35).
