Actually it it set it in order, who are the just? They are the justified and they shall live by faith and Jesus is the one that placed the new birth before faith, John 3:3 “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
Paul also teaches the same Ephesians 2:4-5 “But God, who is rich in mercy, because of His great love with which He loved us,5 even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved),”
Why did He make us alive when we were dead in tespasses, because of the great love with which He loved us and He is rich in mercy towards those He loves. He demonstrated His love towards the world by giving up His only Son, bit shows His love towards us by making us alive while we are dead in trespasses and cannot see the kingdom of God. He opens the minds that the god of this world has blinded and makes spiritually dead people that cannot understand spiritual things or His kingdom, makes them alive so they can see the kingdom of God. Once they see the kingdom they can be born of water and the Spirit to enter the kingdom of God.
I Corinthians 2:14 “But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned.”
II Corinthians 4:3-4 “And even if our gospel is veiled, it is veiled to those who are perishing.4 In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.”
The pronoun here "us" is not speaking of the world, but it is speaking of His people/sheep/Church/elect. Because of that great love of which He loved us, He made us alive so that Ephesians 2:6-7 “6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus,7 so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus.”
Showing His “immeasurable riches of his grace in kindness toward us” since He loves us with a great love now we can see the kingdom be born again so that we can enter the kingdom, but while we are living on earth we are justified and live by faith, that is where verses 8-9 are “8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God,9 not a result of works, so that no one may boast.”
We are saved or justified by grace, being justified we live as Habakkuk said in 2:4 by faith as both Habakkuk and Paul says here is Ephesinas 2:8 and Romans 1:17, Galatians 2:16, 3:11-12 and Hebrews 10:38. The just or justified shall live by/in/through faith and what is even more beautiful is He gives us that faith. Romans 12:3 “For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned.”
Romamns 12:3 “For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith.”
That great love with which He has loved us has the “immeasurable riches of his grace in kindness toward us” that is a beautiful thing that the Lord of the universe loves us to the point that He makes us alive to see/understand/discern the kingdom of God that we can be born again to enter the kingdom of God, Hallelujah praise the Lord of all creation!!!
