That is pure baloney, and I am amazed you can convince your own self of such a thing. Piper absolutely said we are not chosen or elected because we will believe. That puts you outside Christ right there. Faith in Christ is not required, isn't that why you call it "unconditional election"??
He says that a person is chosen or elected in order to believe.
According to Piper our eventual belief is a result of our having been chosen, not the cause of our being chosen.
You are clearly railing against something you don't understand. Faith in Christ
is required. But that faith is not required in order to be elected, it is required in order to be (finally) saved.
It is called unconditional election because it is not based on foreseen faith. Foreseen faith is a condition. So Arminians believe in conditional election--God saw who would believe of their own free will and, therefore, elected them. Calvinists reject this--mostly based on a proper understanding of "Foreknowledge."
The root of your misunderstanding is that you believe grace is a reward. This belief of yours puts you far outside the mainstream of orthodoxy...and it may imperil your soul.
The scriptures teach the opposite, that when a person believes on Christ, then God chooses or elects that person. It is because of Christ's merit that we are accepted. Jesus is God's elect or chosen one, and when we believe we become part of his body and so become elect.
Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.
The scriptures say God has "chosen us in him" and that "he hath made us accepted in the beloved". It is only after you are in Christ that you are chosen and accepted, not before as Calvinism falsely teaches. This is serious error.
There is no possible way that you are correct--whether in Greek or the King's English.
In this passage, whom has God chosen? Is it Christ as you suggest? No, it is "us."
In verse 5, who is predestined? Believers.
Here's a simple question: If we are chosen after we believe in Christ, how, then, are we chosen before the foundation of the world?
Furthermore, in Chapter 2, there is a list of things that God did to the "elect" "In Christ." He made us alive, He raised us up, and seated us with Christ in the heavenly places. God is the one who did these things and they were done "in Christ." In Christ simply means that the elect were somehow present with Christ when God did all these things to Christ. So, when God poured out His wrath for our sin on Christ, we were, in some way, present "in Christ" so that, figuratively speaking, God's wrath was poured out on us "in Christ" (because Christ was standing as our substitute). And all the other things--being made alive, being raised up, etc. are part-and-parcel.
I don't expect you to understand this. It seems you are unable or unwilling to do so.
