Did Jesus believe in a God Who would have kept Him safe if He had jumped off of the pinnacle of the Temple?
I'm sure He did.
So did He jump?
Nope. "You shall not put the Lord your God to the test." (Luke 4:9-12)
You using Satan's argument. Except Satan made a stronger one, since he used scripture:
“‘He will command his angels concerning you, to guard you,’
and
“‘On their hands they will bear you up, lest you strike your foot against a stone.’”Shall we yield to the temptation of Satan or follow in the example of Christ?
Did Jesus believe in a God who could save him out of death? I'm sure he did.
And did he, even being Son (of God), learn, through the things he suffered. the obedience?
What obedience was that? The obedience of Rom 5:19 through which comes righteousness?
Rom 5:19 for as through the disobedience of the one man, the many were constituted sinners: so also through the obedience of the one, shall the many be constituted righteous.
Is that the same righteousness which is, by (Or, out of) faith? Out of Faith, being faith being in the genitive.
Gal 3:24 so that the law became our child-conductor -- to Christ, that by faith we may be declared righteous,
Did the Son of God learn, Obedience of Faith?
I believe the phrase:
The just shall live by faith. Romans 1:17 Gal 3:11 Hebrews 10:38
Is the fulfillment of prophecy relative to the Son's learned obedience. Hab 2:4 Behold, he whose soul is not upright in him shall fail, but the righteous shall live by his faith.
We will be declared righteous to live, out of faith of him.
Luke 24:27 And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.
