Indeed, God establishes leaders - and nations - according to His own will. Daniel 2 is a clear example.
Moreover, I am absolutely certain that nothing can happen in the life of a Christian without either a) God's doing it, or b) God's permitting it.
For ye are dead, and your life is hid with Christ in God. - Colossians 3:3
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. - Galatians 2:20
What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own? - I Corinthians 6:19
I agree that we have been bought with a price and that we are no longer our own. Christians have what the hymn calls "blessed assurance". His Spirit testifies with our spirits that we are children of God.
As to believing Him about this election, I simply repeat that there are more than 2 choices.
Obama: pro-abortion, pro-gay, anti-Israel.
Romney: pro-abortion, pro-gay, pro-Israel.
Goode: pro-life, pro-natural, pro-Israel.
Which of those candidates most meets your beliefs, A-G?
Why not say -- as we are being slanderously reported as saying and as some claim that we say -- "Let us do evil that good may result." Their condemnation is deserved.
The Apostle Paul specifically rejects "doing evil so that good may result".
The entire case about Israel is summarized by Paul in Romans 9-11. This passage in Romans 11 is critical:
Romans 11:25 I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in. 26 And so all Israel will be saved, as it is written: "The deliverer will come from Zion; he will turn godlessness away from Jacob. 27 And this is my covenant with them when I take away their sins." 28 As far as the gospel is concerned, they are enemies on your account; but as far as election is concerned, they are loved on account of the patriarchs, 29 for God's gifts and his call are irrevocable. 30 Just as you who were at one time disobedient to God have now received mercy as a result of their disobedience, 31 so they too have now become disobedient in order that they too may now receive mercy as a result of God's mercy to you. 32 For God has bound all men over to disobedience so that he may have mercy on them all.33 Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! 34 "Who has known the mind of the Lord? Or who has been his counselor?" 35 "Who has ever given to God, that God should repay him?" 36 For from him and through him and to him are all things. To him be the glory forever! Amen.
