Absolutely not. They are not the same. Gabriel of the bible was sent to proclaim the Word made flesh! GOD! Gabriel of the quran denied that. Only the evil one. The great deceiver has so much to gain from the rejection of Christ as the Son of God. The redeemer of the world.
Correct. And the Bible says that the one thing to be certain is that God will not lie to us.
“Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope offered to us may be greatly encouraged.” Hebrews 6:17-18
We are told in the book of Titus that God will not lie to us:
“a faith and knowledge resting on the hope of eternal life, which God, who does not lie, promised before the beginning of time,” Titus 1:2
And quite often in Islamic texts we are told that either Allah is a ‘plotter and planner’, a deceiver. Or that Muhammad lied in order to get what he wanted, or to advance Islam. And Muhammed told his followers to lie if it benefitted them.
And to tie this back to Gabriel, God did not send Gabriel to Mary and tell her one thing or to mislead her and then to Muhammad with a different message.
And Gabriel was not a spirit that showed force or violence anywhere he is mentioned in the Bible, but Muhammad mentioned that this spirit squeezed him and frightened him. Now wouldn’t that be ironic that a young woman, Mary, was not frightened of this spirit but Muhammad, an old man, was? Mary was getting a message that she is going to bear a child in a time when being unmarried and pregnant would be then end of her while an old man was afraid who had nothing to lose?
The whole scenario of Muhammad and this force is suspect. Or the whole description of Allah is also suspect.
