Before we even think about studying hilasterion and the related words hilaskomai and hilasmos, we must address the three cornerstone words of salvation - propitiation, the means of salvation, redemption, the act of salvation, and reconciliation, the result of salvation. Our word study below enters into the arena of the means of salvation, which is Jesus Christ.
Hilasterion
Our best understanding is that hilasterion referred to the lid of the ark of the covenant, which was sprinkled with blood, and thus referred to as the mercy seat. Articles on its meaning are filled with classic words like expiation, atonement, and propitiation, all of which convey almost nothing to the modern reader. In a nutshell, under the Old Covenant, the blood of animals was sprinkled on the hilasterion on the day of atonement to provide temporary reconciliation with God and avoidance of the wages of sin. Under the New Covenant, Jesus, covered with His precious blood, has become our "hilasterion" (and our blood sin offering) as the means of everlasting reconciliation with God and avoidance of the wages of sin.
Three related Greek words (Hilasterion and Hilasmos-nouns and Hilaskomai -verb) appear 6 times in the New Testament, Romans 3:25, Hebrews 9:5 ; 1 John 2:2, 1 John 4:10, Luke 18:13, and Hebrews 2:17. If we look at several translations we find the words translated as (1) propitiatory sacrifice; (2) propitiation; (3) mercy seat; (4) atonement and (5) atoning sacrifice for the nouns; with the verb being translated as (1) have mercy; (2) be merciful; (3) turn your wrath; and (4) make propitiation.
In short the verb refers to the act of having mercy and the noun to the means of having mercy. Therefore hilasterion should be understood as the means of obtaining mercy , i.e the propitiatory shelter.

Much more then, being now justified by his blood, we shall be saved from wrath through him. Romans 5:9 Through the obedience unto death, the shed blood, wherein was the soul of the flesh, of the sinless Son of God, born of woman, the wrath of God was satisfied thus the man could be justified.
Man by that death is reconciled to God and shall be saved (vi Fut Pas 1 Pl) in the life of him. Rom 5:10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. --- That is by his resurrected life or this verse; And if Christ be not raised, your faith is vain; ye are yet in your sins. 1 Cor 15:17, would have no truth to it.
for since through man, the death, also through man, a rising again of the dead, YLT 1 Cor 15:21, I inserted a comer after each word, "man," and removed the word, "is". I believe it to be clearer that way.
Jesus. the sinless Son of God, born of woman, died for our sins and the sin of Adam, the wrath of God was satisfied, and God the Father raised Jesus the Son, from the dead.
That is the facts whether anyone believes it of not. That and that alone authored, eternal salvation. Heb 5:9 That is how anyone who shall be saved, was saved, whether they believe it or not. Inclusive it that above whether it is believed or not is, "to the for grace, through the faith, is the gift of God, ye are ones having been saved (vp Perf Pas Nom Pl m)," inclusive also is,
"according to mercy (The Father before placed Jesus the Son, born of woman, " propitiation," believing he would obediently shed his blood,> [through the faith in the blood of him], which the Son did satisfying the wrath of God),
by washing of regeneration and renewing of Holy Spirit, he saves us. ( vi Aor Act 3 Sg)
by washing of regeneration and renewing of Holy Spirit -- compare with -- This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Spirit
He saves us -- he hath shed forth this, which ye now see and hear.
Presently I believe God is taking out of the nations a people for his name and pouring on them the first fruit of the Spirit, the Spirit of adoption, begetting them as a kind of first fruit of his creatures, so says the word of God.
