I think God can make a rock too heavy for his divinity to carry alone but could just end up lowering himself to a creature to pick that rock up. it shows both how he restrains himself from forcing his ways upon us and of how he is willing to save us and does indeed love us. I think that being a mortal creature is what happens when true being degenerates partially into non-being but that God did not care and decided to play with us in this endless dialogue of love. so life goes on in his divine plan:
Acts 17:22-31 (YLT)
And Paul, having stood in the midst of the Areopagus, said, `Men, Athenians, in all things I perceive you as over-religious; for passing through and contemplating your objects of worship, I found also an erection on which had been inscribed: To God--unknown; whom, therefore--not knowing--ye do worship, this One I announce to you. `God, who did make the world, and all things in it, this One, of heaven and of earth being Lord, in temples made with hands doth not dwell, neither by the hands of men is He served--needing anything, He giving to all life, and breath, and all things; He made also of one blood every nation of men, to dwell upon all the face of the earth--having ordained times before appointed, and the bounds of their dwellings-- to seek the Lord, if perhaps they did feel after Him and find, --though, indeed, He is not far from each one of us, for in Him we live, and move, and are; as also certain of your poets have said: For of Him also we are offspring. `Being, therefore, offspring of God, we ought not to think the Godhead to be like to gold, or silver, or stone, graving of art and device of man; the times, indeed, therefore, of the ignorance God having overlooked, doth now command all men everywhere to reform, because He did set a day in which He is about to judge the world in righteousness, by a man whom He did ordain, having given assurance to all, having raised him out of the dead.'
God restrains himself for the sake of freedom, innocence, goodness, mercy, playfulness, wisdom, and love. this shows Gods nature compared to the somewhat erroneous perception of God that the jews and the greeks had:
Matt 26:51-56 (YLT)
And lo, one of those with Jesus, having stretched forth the hand, drew his sword, and having struck the servant of the chief priest, he took off his ear. Then saith Jesus to him, `Turn back thy sword to its place; for all who did take the sword, by the sword shall perish; dost thou think that I am not able now to call upon my Father, and He will place beside me more than twelve legions of messengers? how then may the Writings be fulfilled, that thus it behoveth to happen?' In that hour said Jesus to the multitudes, `As against a robber ye did come forth, with swords and sticks, to take me! daily with you I was sitting teaching in the temple, and ye did not lay hold on me; but all this hath come to pass, that the Writings of the prophets may be fulfilled;' then all the disciples, having left him, fled.
Luke 9:52-56 (YLT)
and he sent messengers before his face, and having gone on, they went into a village of Samaritans, to make ready for him, and they did not receive him, because his face was going on to Jerusalem. And his disciples James and John having seen, said, `Sir, wilt thou that we may command fire to come down from the heaven, and to consume them, as also Elijah did?' and having turned, he rebuked them, and said, `Ye have not known of what spirit ye are; for the Son of Man did not come to destroy men's lives, but to save;' and they went on to another village.
