Dan 4:35, And all the inhabitants of the earth are reputed as nothing; and he doeth according to his will in the army of heaven, and among the inhabitants of the earth; and none can stay his hand, or say unto him, What doest thou? Do you believe that what he said is true? That he does according to his will(and you say his will is that all mankind should be saved)among the inhabitants of the earth(is that not all mankind?) And you are saying that the inhabitants of earth can stay his hand because they reject him! Are they more powerful than God? Jesus did not die for all mankind, only those that God gave him. If he wants all mankind to be saved, and he accomplishes all his will, why are not all mankind among those that he gave to Jesus? It is a simple deduction. Isaiah 46:10, My counsel (purpose) shall stand, and I will do all my pleasure. Is it his purpose to save all mankind? Then why does he not do it? If it is his pleasure that all mankind be saved, then why does he not save them? You say it is because they reject him (stay his hand). He says that they can not stay his hand. The conclusion is that IT IS NOT GOD'S WILL TO SAVE ALL MANKIND.
"It is a simple deduction." (It is actually not a simpe deduction)
"The conclusion is that IT IS NOT GOD'S WILL TO SAVE ALL MANKIND." (The wrong conclusion . . .)
You are using man's reasoning to try to understand God and are not taking the Bible at face value at what it says about God. The problem is not with the Bible, it is with your view of what it says.
