Hmmm... I hope it is not being suggested God is limited. I hope it is not being suggested there are occasions when God CANNOT do but one thing and one thing only.
Yes, but that misses my point(s). The point of discussion pertains to the monergism or synergism of divine mercy and compassion. A proper Christology does not compare Jesus to sinful humanity. It does not quantify or qualify Jesus' compassion with comparison to creaturely dependence on the Creator, especially not in a post-disobedient state. The post-redemptive or -regenerate state is not the correct measure, either because Jesus was never in any of those states. The closest anyone can come is to say that we are compassionate because the Spirit of God is at work within us to be that way but 1) the Spirit at work within Jesus is the same Spirit as God's, 2) Jesus commands that Spirit, and 3) that Spirit is never working in a sinful, estranged Jesus. Any so-called "synergism" that exists is one only of Person, not kind. Both the Son and the Spirit are identically divine. That is not the case with both the man and the Spirit. Our dependence on God and the Son's dependence on God is not identical.
And for the record, God could have done anything he liked. His Father, too.
Matthew 26:51-54
51And behold, one of those who were with Jesus reached and drew his sword and struck the slave of the high priest and cut off his ear. 52Then Jesus said to him, “Put your sword back into its place; for all those who take up the sword will perish by the sword. 53Or do you think that I cannot appeal to My Father, and He will at once put at My disposal more than twelve legions of angels? 54How then would the Scriptures be fulfilled, which say that it must happen this way?”
A day later he was dead. That did not happen because he had no choices and no power to do anything other than be murdered. It did not happen because it was the only thing he could say or do. Jesus said and did only what the Father instructed, but the Father could have done any number of things, including rid the entire planet of sinful man and start over. He could have even wiped the planet clean, started over and then credited whatever salvation was accomplished with the start-overs back to the prior creatures who lived by faith. God is not limited by sin, and He most definitely is not limited by time, space, or circumstance.
Post 19 does not apply to Jesus.
Post 22 does not apply to Jesus. Jesus, and Jesus alone, is free in the absolute sense, and Jesus alone can transcend even the most determinative temporal causes within creation.
Luke 22:41-42
And he withdrew from them about a stone’s throw, and He knelt down and began to pray, saying, “Father, if You are willing, remove this cup from me; yet not my will, but Yours be done.”
Do you think his Father would have said, "Do it anyway. Do it against your will because My will is what matters and you do not have any choice or say in the matter," had Jesus told his Father he did not want to go? Is that what we're supposed to understand from Luke 22's plea?
