Q #2 , Christians, what to you, are the *foundation* or?

Christ is the foundation it has already been laid, any other foundation when the rain and the storms comes it wll fall. Jesus died on the cross to take away the sins of the whole world never to see them again. and is now offering life to all who come to God through faith in Jesus, why do we need life because we are all born into this world dead in our sins (romans 5:12) receiving the offer of Life (1 john 5:11,13)
