WCF 8.5.
The Lord Jesus, by His perfect obedience, and sacrifice of Himself, which He through the eternal Spirit, once offered up unto God, hath fully satisfied the justice of His Father; (Rom. 5:19, Heb. 9:14, 16, Heb. 10:14, Eph. 5:2, Rom. 3:25–26) and purchased, not only reconciliation, but an everlasting inheritance in the kingdom of heaven, for all those whom the Father hath given unto Him. (Dan. 9:24, 26, Col. 1:19–20, Eph. 1:11, 14, John 17:2, Heb. 9:12, 15)
