I'll disagree with some others here and say that I believe Jesus could have sinned.
I don't see anything controversial in stating that Jesus could sin. If He was fully human, it would mean that He too shared a disposition to sin-- yet, because He
submitted His free will wholly unto God, He chose never to sin of His own volition.
Let's think about free will based purely off of a logical perspective for a second.
Remember that our God is a God of love and justice. Think of Micah 6:8, John 3:16, and 1 John 4.
Next, consider the hell that I am sure most of you believe in. I happen to think it is a misconstrued and badly evolved doctrine, but I will assume it is true for the purposes of this discussion.
Then, the Bible repeatedly states that "The Lord... is patient with you, not wanting
anyone to perish, but
everyone to come to repentance" (2 Peter 3:9). This is asserted time and time again, and I am sure you can read your own Bibles to know this.
Consider these facts together, in a less organized philosophical syllogism.
We serve a God of love.
He is not willing that any should spend eternity in damnation.
But, given that there is no free will, He controls whether or not a person sins.
So, God sends some to an eternity in damnation arbitrarily.
But, God cannot will that no one spend an eternity in damnation and also that some spent an eternity in damnation, for He would be in a state of contradiction.
But God cannot be in a state of contradiction.
So, the assertion that God controls whether or not a person sins cannot be true.
And at this point, the anti-Free Will party will argue, "It is for God's glory," and "His ways are beyond our ways." But surely, God gave us an intellect for a reason. It is not the Jewish tradition that Jesus knew nor the Baptist tradition we should follow to simply stop questioning God. Our quest is to become more like God, and I believe that in it, we will know more of Him. The greatest example of God ever was also the most kind and loving person ever to walk the earth--so how is it that God could then arbitrarily have a system of judgement that flies in the face of our Scriptures?
Either God is in contradiction, or you have some bad theology, my anti-Free Will friends.
