On this rock I will build My church. The
rock is an Old Testament title for the Messiah (Exod. 17:6; Num. 20:8; Deut. 32:4; Psalm 18:2; 1 Cor. 10:4). The Church will be built on the confession of Jesus as Savior (Rom. 9:33; 10:9-13; Eph. 2:20; 1 Pet. 2:6-8). Jesus speaks of the Church as a future company that is distinct and separate from Israel.
The gates of Hades [Hell]shall not prevail against it.This refers to the power of Satan over men through death (Heb. 2:14-15). Jesus would conquer death and Hell (1 Cor. 15:54-57; Rom. 8:37).
