24 being justified freely by His grace through the redemption that is in Christ Jesus,
by [the instrument of justification is grace] His [emphatic] grace
The Holy Spirit uses the word “grace” 24 times in Romans (in Greek). God gives justification freely through the principle of grace. Grace is what God does for us rather than what we do for Him. It is favor with no strings attached. Grace is God’s outreach toward us unconditionally; there is no work by us involved in God’s justification of our souls. Grace is something that God does and not what we do. It is something that God does on our behalf.
Grace is the work of both the Father and Christ Jesus. There are no strings attached to what God did through Christ for us.
Grace is all that God is free to do for us because of the person and work of Christ.
Salvation is the justification of sinners and the ungodly. It is a work of God whereby God does the doing. Salvation is not a work in us but grace from Him. Pleading with God does not save us, for that would be a form of work by us. It is not our works or our character that impresses God. God’s grace recommends His salvation for us.
Ro 4:5, But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness,
Salvation is free for the sinner but it was anything but free for God. Jesus paid the ultimate price for our sin—death on the cross.
