Greetings again Dave. Thank you for your thoughtful post and your gracious attempt to understand my ramblings.
It's different for us. Paul said that while He desired to do good, he was incapable of doing it. Here also, the desire isn't free, because the character constrains.
I agree that mankind in their depravity is not free, i.e., they are slaves to sin. I further agree that mankind, after salvation and regeneration, may have two natures. Which is then to be fully restored to one nature after the resurrection. Therefore, the desires of the flesh are still strong as our desires of the spirit grow.
You suggest that it is Paul's character that restrains him. But I think it is Paul's finiteness that restrains him. I suppose we could agree that it is Paul's finite character that restrains him. A finite character can be restrained by a more superior character, even if that superior character is also finite. Thus how Satan makes us slaves to sin through deception even though he is also of finite character.
But God is not finite in any way. He is not conflicted by two natures, not restrained by finiteness (because He is infinite and Omni-everyting). Nothing therefore constrains or restrains God. He is the very definition of free.
Romans 7:18 For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find.
Jesus said the same thing when He stated that a good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Remember, when He was called good, His reply, in His humanity, was "why do you call me good, God alone is good.". God is the good tree, that's why anything good that comes from us is an undeserved gift from God, the fruit of the Spirit. The flesh cannot do anything good by righteous standards. It can desire it, but cannot do it. Jesus, in answering some who did not believe Him, said, if you do not believe, then believe the works that I do, so that you may know that I Am He. You can tell a tree by it's fruit. Now God can do all things, but only in result. We see the constraint in action at the cross. God's justice must be satisfied. Jesus must be sinless for atonement. Jesus had to fulfill everything according to the Law for us, in our place. All the prophecies must be fulfilled. All so that we could have the relationship restored with God through Jesus that we lost through Adam.
All this seems to be about finite human beings and the flesh. Which I agree, mankind is retrained and constrained by various factors. But using the finite as an example of the infinite seems misused.
God cannot lie (Titus 1:2, Hebrews 6:18), He cannot be tempted by evil (James 1:12), or deny Himself 2 Timothy 2:13). God's desires are grounded in His nature. He is constrained by His character.
It seems to me that the Titus 1:1-2 verse is one of assurance of faithfulness not a lesson of God's limitations of constraint. It is written that God "who cannot lie" as an assurance that God is faithful and true in our "hope of enteral life" which God "promised before time began" (Tit 1:2). Which basically means God is consistently God, eternally. Never stopping to be God, never ending to be consistent. Thus one can count on that fact.
To bring in a Thomas Aquinas term but my own logic, God not being able to be a 'privation' of His own self attributes, isn't a limitation. I guess one could say that God could not be the absence of Himself. But that just sounds like nonsense.
He cannot be tempted by evil (James 1:12)
Yes, I agree. God is infinite and there is no power greater than God to tempt Him or overcome Him into being something He is not. Because He is not flawed and is infinite, He is free to be that which He desires and not being overcome by something He does not desire. But Paul, being finite, is sometimes overcome and does that which He does not wish to do.
or deny Himself 2 Timothy 2:13)
This seems to support my position more. That is, what is this freedom that would affirm that freedom is the denying of one's self? It seems to me that the very fact that one deny's themselves is proof that one is not really free. Only those who are slaves, deny themselves at the expense of who they really are. We, as slaves to sin, deny ourselves and who we really were created to be. This denying of one's self is not freedom, but slavery.
I guess one could say that because God cannot deny Himself, He cannot be a slave. But what sense does it make to say this is God not being free? Or that God is restricted in some way because He cannot be a slave?
But then I muse about the Incarnation and Christ coming as a servant to others. I wonder if God can even become a slave through the incarnation, thus even dispelling this supposed restraint or restriction.
Great conversation Dave...
Peace, Grace, and hope to you.
