The Punishment Which God's Justice Requires
God is not only supremely merciful, but also supremely just. His justice requires (as He has revealed Himself in the Word) that the sins we have committed against His infinite majesty be punished with both temporal and eternal punishments, of soul as well as body. We cannot escape these punishments unless satisfaction is given to God's justice.
The Satisfaction Made by Christ
Since, however, we ourselves cannot give this satisfaction or deliver ourselves from God's anger, God in His boundless mercy has given us as a guarantee His only begotten Son, who was made to be sin and a curse for us, in our place, on the cross, in order that He might give satisfaction for us.
The Infinite Value of Christ's Death
This death of God's Son is the only and entirely complete sacrifice and satisfaction for sins; it is of infinite value and worth, more than sufficient to atone for the sins of the whole world.
Reasons for This Infinite Value
This death is of such great value and worth for the reason that the person who suffered it is — as was necessary to be our Saviour — not only a true and perfectly holy man, but also the only begotten Son of God, of the same eternal and infinite essence with the Father and the Holy Spirit. Another reason is that this death was accompanied by the experience of God's anger and curse, which we by our sins had fully deserved.
The Mandate to Proclaim the Gospel to All
Moreover, it is the promise of the gospel that whoever believes in Christ crucified shall not perish but have eternal life. This promise, together with the command to repent and believe, ought to be announced and declared without differentiation or discrimination to all nations and people, to whom God in His good pleasure sends the gospel.
Unbelief Man's Responsibility
However, that many who have been called through the gospel do not repent or believe in Christ but perish in unbelief is not because the sacrifice of Christ offered on the cross is deficient or insufficient, but because they themselves are at fault.
Faith God's Gift
But all who genuinely believe and are delivered and saved by Christ's death from their sins and from destruction receive this favour solely from God's grace — which He owes to no one — given to them in Christ from eternity.
The Saving Effectiveness of Christ's Death
For it was the entirely free plan and very gracious will and intention of God the Father that the enlivening and saving effectiveness of His Son's costly death should work itself out in all His chosen ones, in order that He might grant justifying faith to them only and thereby lead them without fail to salvation. In other words, it was God's will that Christ through the blood of the cross (by which He confirmed the new covenant) should effectively redeem from every people, tribe, nation, and language all those and only those who were chosen from eternity to salvation and given to Him by the Father; that He should grant them faith (which, like the Holy Spirit's other saving gifts, He acquired for them by His death); that He should cleanse them by His blood from all their sins, both original and actual, whether committed before or after their coming to faith; that He should faithfully preserve them to the very end; and that He should finally present them to Himself, a glorious people, without spot or wrinkle.
The Fulfillment of God's Plan
This plan, arising out of God's eternal love for His chosen ones, from the beginning of the world to the present time has been powerfully carried out and will also be carried out in the future, the gates of hell seeking vainly to prevail against it. As a result the chosen are gathered into one, all in their own time, and there is always a church of believers founded on Christ's blood, a church which steadfastly loves, persistently worships, and
— here and in all eternity — praises Him as her Saviour who laid down His life for her on the cross, as a bridegroom for His bride.
