"The suretyship of Jesus is the assurance that God will keep his salvation covenant with his people. God has made a covenant of grace with us through the Lord Jesus Christ. "By so much more Jesus has become a surety of a better covenant" (Heb. 7:22). Salvation isn't the result of some kind of an agreement between sinners and God. It's the result of an eternal covenant between the Father, the Son, and the Spirit. Because of this eternal covenant, salvation involves all three Persons in the Godhead (Eph. 1:3-14; 1 Peter 1:2)."
