Римлянам 5:10

For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being now--"having now been" reconciled, we shall be saved by his life--that is "If that part of the Saviour's work which cost Him His blood, and which had to be wrought for persons incapable of the least sympathy either with His love or His labors in their behalf--even our 'justification,' our 'reconciliation'--is already completed; how much more will He do all that remains to be done, since He has it to do, not by death agonies any more, but in untroubled 'life,' and no longer for enemies, but for friends--from whom, at every stage of it, He receives the grateful response of redeemed and adoring souls?" To be "saved from wrath through Him," denotes here the whole work of Christ towards believers, from the moment of justification, when the wrath of God is turned away from them, till the Judge on the great white throne shall discharge that wrath upon them that "obey not the Gospel of our Lord Jesus Christ"; and that work may all be summed up in "keeping them from falling, and presenting them faultless before the presence of His glory with exceeding joy" (Jde 1:24): thus are they "saved from wrath through Him."

The apostle, having made good his point, and fully proved justification by faith, in this chapter proceeds in the explication, illustration, and application of that truth. I. He shows the fruits of justification (Rom 5:1-5). II. He shows the fountain and foundation of justification in the death of Jesus Christ, which he discourses of at large in the rest of the chapter.

5:10 saved through the life of his Son: Believers already share in the new life that Christ provided through his resurrection (6:11). Through this vital connection with Christ, believers will also be spared from God’s wrath in the last day (see also Col 3:4).
