The Iglesia Ni Cristo believes that membership in the Church Of Christ is the only means for people to receive the salvation that the Savior Jesus Christ brings. All people need salvation, for all have sinned, hence, all of mankind are to die in the lake of fire, the wages of sins (Rom. 5:12; 6:23; Rev. 20:14). For people to be saved, he should enter in by Christ, by becoming a member of His body or Church (John 10:9; I Cor. 12:27; Col. 1:18) because it is His Church that Christ will save (Eph. 5:23).

Christ will not save anyone outside the Church Of Christ because it would be against the law of God. His law requires that sinners should pay for their own sin (Deut. 24:16; Rev. 20:14).
