YHWH is our only Saviour before the Cross. Ias 43:11.

Jesus Christ is this YHWH. Zechariah 2:8-11.

The presence of Chris on this earth from his incarnation to His resurrection, especially the issue of the cross, was merely a manifestation of eternal salvation given from the foundation of the world. See 1Tim 1:9,10, 1Pet 1:18-20. Tit 1:2,3.

The meaning of the death of Christ saves us, not the physical death of Christ.

Christ's death means sufferings.

Christ's death means the gift of His life.
