John 3:18

“He that believeth on him is not condemned, etc.] Whether Jew or Gentile, because a believer is openly in Christ; and there is no condemnation to those that are in him: and though the sentence of death passed upon all in Adam, and judgment came upon all men to condemnation in him; yet this sentence being executed on Christ, the surety of his people, who has been condemned to death, and has suffered it in their stead, his death is a security to them from all condemnation: and they are delivered by him from the curse and condemnation of the law: and having in conversion openly passed from death to life, they shall never enter into condemnation; and this is the happy case of every one that…”
