The atonement that Christ made upon the cross when He died is the:
Source of all our spiritual blessing
In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace
(Ephesians 1:7)
Separating power in holiness
So Jesus also suffered outside the gate in order to sanctify the people through his own blood.
(Hebrews 13:12)
Spring in service
For the love of Christ controls us, because we have concluded this: that one has died for all, therefore all have died; and he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised.
(2 Corinthians 5:14)
Success in conflict
And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
(Revelation 12:11)
Solace in trouble
looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God. Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted.
(Hebrews 12:2-3)
Sufficiency in glory
I said to him, “Sir, you know.” And he said to me, “These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb.
(Revelation 7:14)
