I, I am the LORD (YHVH), and besides me there is no savior. -- Isaiah 43:11 (ESV)

And Jesus is "the Lord our Saviour" (Philippians 3:20; 2 Peter 1:11, 2:20, 3:18; Acts 13:23; Titus 1:4), therefore some argue, this proof Jesus is the Almighty God, YHVH.

However, Isaiah specifically refers to the instance where only the LORD was able to save Israel from Egypt (Exodus 14:21):

Thus says the LORD, who makes a way in the sea, a path in the mighty waters, who brings forth chariot and horse, army and warrior; they lie down, they cannot rise, they are extinguished, quenched like a wick. -- Isaiah 43:16 (ESV)

It could also be understood that Isaiah might have been referring to God saving us eternally by the forgiveness of sin:

I, I am He who blots out your transgressions for My own sake, and I will not remember your sins. -- Isaiah 43:25 (ESV)

Both these scriptures are in the same context and both cases would not have been possible if it was not for an act of God.

What can save us

Some scholars assume that only God can save us. While this is true in regard to God's authority to decide who may be eternally saved, one is also "saved" by God's messengers who introduced God. Often "saviours" in the bible is normal humans, for example Nehemiah 9:27; 2 Kings 13:5; Obadiah 21.

It is both correct to say that Jesus "saves us" (who taught the gospel, revealed God's word, trained his disciples, gave himself as a sacrifice, forgiveness our sin and still intercedes for us (Romans 8:34)) as well as to say that God the Father is "our Saviour" because He enable Jesus to do so. Therefore, there is no problem to refer to both God the Father and Jesus the Son of God as our Saviours.

Salvation belongs to

1. our God who sits on the throne, and
2. to the Lamb!

-- Revelation 7:10 (ESV)

Bad translations

Titus 2:13

the glorious appearing of our great God and Savior, Jesus Christ -- Titus 2:13 (NIV)

The translators of the NIV, KJV and AMP implies that "our great God" is also "our Saviour, Jesus Christ". However, this verse is incorrectly translated by biased translators in NIV, KJV, AMP. Other bibles like RV, ASV, NAS, Moffatt, RSV, NRSV, Douay, New American Bible, NEB translate the same verse:

appearing of the glory of the great God and our Saviour Jesus Christ -- Titus 2:13 (ASV)

This version implies that "the great God" and "our Saviour Jesus Christ" are two different persons, i.e. Jesus Christ is God's glory, not God Himself.
