If Jesus Wouldn't have received the Holy Spirit at his Baptism.Would he have beat the devil?
I think what you really want to know is, if Jesus did not have Holy Spirit, would he have resisted the devil and remained faithful to his father.
That's quite an interesting question.
I would say yes, based on the fact that others who did not receive holy spirit, resisted the devil, and remained faithful.
The only thing that would have been lacking, is his ability to perform powerful works, read minds, and have an extreme level of wisdom.
Other than that, I believe he would have done the same things he did, because 1) he loved his father, 2) he loved righteousness, 3) he loved God's word, in scripture. He also knew what a wicked, evil, cold-hearted, deceitful liar, his brother (angel Satan) was.
Would he have controlled his anger, and not feel like wrapping his hands around Satan's neck, and strangling the life out of him?
Yes. For sure, because we imperfect men do, and we know it's impossible for
any human to fight Satan... physically.
