What does the Bible say about Jesus being our surety?

In Hebrews 7:22, it is stated that 'by so much was Jesus made a surety of a better testament.' This tells us that Jesus took on the full responsibility for the salvation of His people, unlike a mere guarantor who would only supplement the debts we cannot cover. The new covenant represents a profound shift from the old covenant of ‘obey and live; disobey and die’ to one where Jesus solely bears the obligations for our redemption. Our Lord Jesus Christ is the surety who pledges not only to pay our debts but to completely assume them, ensuring that every one of God's elect will be safely brought before the Father.
