Salvation due to christians 

Christian apologists insist that the only way to get rid of sin is by atonement, in this case Jesus’ death and sacrifice on the cross. Now when we read the Bible, just like many other Christological concepts, we find that this concept of sin only being removed by atonement, is not really biblical, and that there are indeed other ways of removing sin.

The only saviour is God

Beside God There Is No Saviour - 

- [For God said,] "I, [even] I, [am]  the Lord; and beside Me [there is] no saviour." (Isaiah 43:11) 

Jesus never said that he came to save humanity 

But he said in John 5 v 30 :

I, Jesus, can do nothing of myself

Which means that he can not save you or even save himself

The ONLY Saviour is Almighty God - Isaiah 43:10-11 

Rely on Almighty GOD ONLY in whom there is Salvation.

Isa 45:5-6:

"I am the LORD, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:

That they may know from the rising of the sun, and from the west, that there is none beside me. I am the LORD, and there is none else."

God loves Justice
