In the scheme of God's eternal purpose, men where chosen and saved before the foundation of the world. However, men are still under a state of judgment until that act of eternity is applied by repentance and faith. Men are not justified because they are elect, they are justified by faith. This is a misconception of the eternal acts of our God. Scripture never places the priority of being Justified by faith with the doctrine of election. While, election provides the assurance for justified believers (Rm 8:29). You never find anything in the NT that states the basis of our justification is election. Romans 8:29, is a beautiful pictures of our assurance in spite of the corrupted hearts of men. Notice, Paul has already stated that creation, ourselves, and even the spirit groans for the glorification of our bodies. Paul, assuring believers, that nothing can separate them from the love of God; emphasizes, that those whom were foreknown were predestined, justified, and will one day be glorified.
However, election saves no one. Why? elect sinners will be demolished without right standing. The doctrine of election does not provide, a perfect judicial righteousness. Only the the gospel provides man's greatest need (i.e My sin for Christs Righteousness). Election is the past act of God whereby before the foundation of the world he choose men of all tongues, tribes, and nations whom he would save.
Those he choose are justified, sanctified, and finally glorified. However, election does not make any believer justified, sanctified, or even glorified.
The answer to this question is an emphatic NO! Believers are not justified before belief . Men are justified when they repent of their sins and place their faith in Christ, as their perfect substitute and perfect righteousness. In fact, elect believers, prior to conversion are still under the condemnation of God (Jn 3, Eph2). These two passages place men, prior to conversion, in a state of damnation. John, places men, as those who hate the light and love the darkness; while, Paul says, believers were once children of wrath (note, before conversion).
Men are changed positionally because of they have placed their faith in Christ. While, they have assurance of their Justification because of the electing love of God.
