Rom 3:24-26 24 Being justified freely by his grace through the redemption that is in Christ Jesus: 25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. Rom 4:5 5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. God is Just in Justifying the Ungodly [while actually being ungodly] because of the redemption provided for them in Christ Jesus their Surety Head. Those Christ died for, His death alone for them put away sin and the consequences thereof, all of its penalties, death included, by making propitiation/satisfaction by His Blood, which is again the propitiation in Vs 25 By this [His Blood] God's Wrath has been appeased, not by their Faith in His Blood, but by His Blood alone God was appeased on their behalf ! And because of this, Christ's blood has so washed away the sins of theirs and its effects, its now so , as if they never sinned, and they are completely Righteous before Him, all of which is solely based on His Precious Blood, and So God Justifies them, even while and when they themselves are personally born into this world in a ungodly state, when they are children of wrath as others Eph 2:3, and while they are with enmity in their minds and heart against God Rom 8:7 7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. Now again, while those Christ died for are in this state of ungodliness, because of Christ's Blood, they are Justified, made Righteous before God, Hence, God Justifieth the Ungodly !
