Yes
Because Christ was the author of faith
He relied on his father
This is our example
With the other concepts of God, outside of this,it says without faith it is impossible to please God.

This is life eternal,that they might know thee,and Jesus Christ whom thou hast sent

Not my words
Clearly the right concept of who God is
and the faith of Jesus is salvational
