Spoken like a Presbyterian Calvinist!
Putting tongues aside (because we have been going over this same ground year after year!), are you saying that every gift of God has to be the sovereign work of God?
So the Scripture, "By grace are you saved, through faith, it is not of yourselves, it is the gift of God", means that if it is gift, salvation came come only through a sovereign work of God?
It is interesting that the 19th Century New England Presbyterian Church believed that, and so they didn't evangelise very much. Finney went against them by telling folks that they had to make a choice and then God would do the work in them.
But a person who may be under conviction of sin (which I believe is a sovereign work of God by the way), if he sits like a wooden Indian and does nothing, is he not still unsaved and will slide down into hell when he dies?
How come Paul says, along with pursuing love, that the Corinthians (and my implication, us), desire the greater gifts? If receiving gifts were just the sovereign work of God, then is not Paul mistaken when he shows that we can choose to desire one gift over another?
Can I ask you another question. I don't know if you have children or not. But if you do, and you discovered that the child had terminal cancer, and that was breaking your heart, wouldn't you be consumed with love for that child and pray, weep, travail before God that He would come and heal her? But wait! That wouldn't do any good, because healing is a gift and it is the sovereign work of God and there is no point in praying and asking God to do it. Wouldn't something like that cause a conflict within you between pleading for the healing, and not pleading for it because you know that God won't answer your prayer because He chooses according to His sovereign will whether He wants to heal her or not.
And if you took her to the elders of the church, as instructed by James so they can lay hands on her and pray the prayer of faith, that may not work, because James is wrong about having the elders do that, because healing is a gift and it is solely according to God's sovereign will and the laying on of hands will be a pointless act.
(In actual fact, that's what most Christians believe even if they lay hands on the sick. They do it because the Scripture tells them to do it, but in their hearts they don't believe God will heal the person anyway and are surprised and amazed if and when He does!)
