Bold letter are mine for discussion ~ This is incorrect, no pun intended, but bringing this up for discussion, for all to better understand the great truths of the scriptures.
Our faith is
the result of "first" being quicken to life, or, when we are born again by the Spirit of God. Our faith has
no part in the legal phase of our salvation from sin and condemnation,
none whatsoever. Jesus Christ's faith and obedience is the
only ground of sinners who were at enmity against God, being made the righteousness of God...... acceptable in His sight.
Jesus Christ
was not a private person acting
only for himself before the law of God while living in this world~he was
the head of an
elect body that was given to him to redeemed by his Father~he acted as their surety from conception until the death of his body, and resurrection to God's right hand of power.
Ephesians 2:4-6
“But God, who is rich in mercy, for his great love wherewith he loved us, Even when we were dead in sins, hath quickened
us together with Christ, (by grace ye are saved

And hath
raised us up together, and
made us sit together in heavenly places in Christ Jesus:”
All this before any of us were born again, and had the power to believe! Our legal justification
is all of God, without us contributing any works whatsoever!
Justification a major part of our salvation, and like the words save/saved/salvation, is used in different senses in the scriptures, and our job is to study to rightly divide its senses, or else, we will end up corrupting God's word.
Example:
Let us look at one of these scriptures:
Acts 13:39 “And by him all that believe are justified from all things, from which ye could not be justified by the Law of Moses.”
This text has to do with justification, not regeneration; but is it conditional at all? All that “believe” (plural, present tense) “are justified” (plural, perfect tense). Not will be, but are, already justified and that by the faith and obedience of Christ alone. Romans 5:19; Galatians 2:16, etc.
Paul further confirmed the fact by ascribing justification
“by him,” that is, by Christ! Paul argued that legal justification precedes faith all through his epistles.
Since it takes place in the subconscious part of man,
where God is the only active person working,
it is without question irresistible. No man knows when he was quicken to life, he may get close, but the exact timing of this birth is hidden from us~we were dead in trespasses and sins~even though loved by God from eternity past, proven that we were by being given life freely for Jesus' sake.
Not legally~legally our justification is freely given to us based on Christ's redemption work.
Romans 3:24
“Being justified freely by his grace through the redemption that is in Christ Jesus:”
There is a "
practical" justification that takes place once we believe and understand the gospel of Jesus Christ, this justification takes place in our hearts/conscience that brings peace to our hearts.
Romans 5:1
“Therefore being justified by faith,
we have peace with God through our Lord Jesus Christ:”
This has not
one thing to do with our legal forgiveness of our sins through Christ's faith and obedience. This justification takes place in our spirit of knowing the truth of the gospel of Jesús Christ, that may take time for one to fully comprehend.
