The gracious gift from the many failures led to justification.
Rom 5:16 NET
“Though your sins have stained you like the color red, you can become white like snow; though they are as easy to see as the color scarlet, you can become white like wool.”—“I, I am the one who blots out your rebellious deeds for my sake; your sins I do not remember. Remind me of what happened! Let’s debate! You, prove to me that you are right!”—I remove the guilt of your rebellious deeds as if they were a cloud, the guilt of your sins as if they were a cloud. Come back to me, for I protect you.
“For this is the way God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life.”—But the gracious gift is not like the transgression. For if the many died through the transgression of the one man, how much more did the grace of God and the gift by the grace of the one man Jesus Christ multiply to the many!—Some of you once lived this way. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
