In Mormonism, a covenant is a sacred agreement between God and his people that is always conditional. Members promise obedience, and in return, God promises blessings. If they fail to keep their covenants, the blessings are withheld, and penalties may follow.
Almost everything in LDS life is considered a covenant. Baptism, confirmation, temple endowment, marriage sealings, and even daily obedience are framed as covenantal commitments. Because of this, covenants are woven into nearly every ordinance and responsibility in the church.
Biblical Christianity teaches that the new covenant in Christ is unilateral (Jeremiah 31:31–34). God fulfills the covenant entirely through Jesus, offering forgiveness and eternal life as a free gift, without conditions based on human obedience.
