I suppose I could if my faith were strong enough. You are asking about a principle of faith that has nothing to do with salvation. The first principle of faith is of action, that is that we do what we believe is true only having the assurance that it's true. That principle is the faith that saves us. Through it, we obtain grace unto salvation.
Your questions reflect faith as a principle of power which Jesus taught that having such faith the size of a mustard seed would enable us to say to this mountain be moved and it would be moved. I have healed the sick. I believe those instances were based on mutual faith and not contrary to the will of God. We can see from the Bible that two prophets contradicting each other is not wise. If I were to pray for rain and another prayed that it not rain, that would be a problem, would it not?
In any case, faith as a principle of power is not required for salvation. If it was, then very few would be saved.
Oh. I disagree. He was human just like us. He was born, just like us and he died just like we will. Was his life just like ours? Maybe not. But he had all the elements of mortality. He could be tempted. He could suffer. He could feel pain. And he could bleed. He was a human as a human could get. The difference wasn't in his body, it was in his spirit. Unlike us, IMO, his spirit managed his body and not the other way around as it is with us. Our body manages our spirit. We know a thing is wrong, but to satisfy our appetite, we choose to ignore what's right and do what's wrong. That was not an issue with Jesus. He was, apparently, afraid of the suffering that he would have to endure, but he did it anyway because it was the right thing to do. His humanity, his body was as human as any of us. The same species as we are. Human DNA through and through.
