Christ is unconditionally condemned by the Father, for his glory, yet the law of God requires that sin and guilt reciprocally imply one another. Therefore Christ, being condemned, but not for any sin he committed, is condemned for the sins of others, whose sins are imputed to him. These are the elect, chosen in Christ for the glory of God.
The law of God requires that sin and guilt, righteousness and innocence, reciprocally imply one another in one person. However, the condemnation of Christ is unconditional, not for sin he himself committed, but for the sins of others. Wherefore, the elect are personally united to Christ, his the guilt, theirs the sin; and because he partook of their sin, they also partake of his righteousness.
And that lawfully, to produce an intuition of the Father, who unconditionally condemned his Son; and of the Son, who bore their sins; and of the Holy Spirit, who is justifies Christ in his submission to condemnation, that the elect may be redeemed for the glory of God.
“Yet it pleased the Lord to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the Lord shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities. Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.” Isaiah 53:10-12
