God doesn't need to control His prophecies. Where do you even get these ideas from? God lives outside of time. He is the beginning from the end. He is at the end of all things as certainly and concretely as He is here in the present with us now.
He doesn't have to control His prophecies, He is at the end right now and sees what is going to happen. Don't you get that? Satan operates inside of time, like we do, so he cannot see the end from the beginning. But God created time, it is no obstacle to Him. Don't bother trying to understand it, we cannot comprehend a fourth dimension from the third, any more than a two dimensional drawing can understand a cube. You just have to accept it.
Regarding the second coming of Christ, that is a good question. There is a simple answer however. Every lease is temporary. And when Adams lease ends, then Christ returns, and all power and all authority is delivered back to God, that He may be all in all.
24Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
25For he must reign, till he hath put all enemies under his feet.
26The last enemy that shall be destroyed is death.
27For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him.
28And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
-1 Corinthians 15:24-28

To understand how the infinite mind of God can collect, collate, and harmonize every bit of data that exists in the universe and make it all work for His will is beyond our comprehension. To get a small grasp on that reality we need to realize that God rules in the world.
Satan tried to have Peter try to keep Jesus from the cross but God determined that Jesus is to die on the Cross. In Matthew 16, Peter says, Lord, dont you do that! Dont go to the cross! and Jesus knew the source and said, Get thee behind me, Satan. Satan knew the power of the Cross and the Death Penalty by the Government which was established by God. "The authorities that exist have been established by God" (see Romans 13). How did God know that the Roman Government will use the "Cross" for their death penalty?
Satan used Judas and the Jewish leaders to kill Jesus. Satan was hoping that the Jewish people would STONE Jesus to death based on the Jewish Law and Custom. But the Jewish leaders were smart enough not to take the law into their hands and asked the Roman Government to crucify Christ.
There is no more graphic account in all Scripture of God's sovereignty than the death of Jesus Christ. God used every creatures combined to kill His Son. He controlled the hated of the Jewish leaders, the hostility of the Romans toward those leaders, the defection of the disciples, the betrayal of Judas, and the denial of Peter. Jesus came into Jerusalem on the very day Daniel prophesied He would (Dan. 9:25). While the people were selecting their Passover lamb, He came as the true Passover lamb. He died on the very day the Passover lambs were slaughtered. Every single detail was covered. And it was all accomplished by the free choice of evil men and demons. But even that was the work of God.
Psalm 115:3--"Our God is in the heavens; he hath done whatsoever he hath pleased."
Psalm 135:6--"Whatsoever the Lord pleased, that did he in heaven, and in earth, in the seas, and all deep places."
Daniel 4:35--"[God] 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?"
Ephesians 1:11--"[He] worketh all things after the counsel of his own will."
There are over three hundred prophecies about the Messiah in the Old Testatment. It is certainly reassuring to know that God has ultimate control of history, especially when current events may lead one to conclude otherwise.
We come from the world's setting that is controlled by God that lead to the fulfillment of a Hebrew prophet's statement that He would be born in Bethlehem; all the way down to the circumstances of His birth, His life, His death, His Resurrection and His Future.
