Jesus died for our sins on the cross. He is risen from the dead for our justification. We become children of God by faith in the Lord Jesus (Galatians 3:26). Jesus intercedes for believers, that the Father will "keep them from the evil one" (John 17:15). This is the present day ministry of Jesus, as every believer's High Priest (Hebrews 7:20-25). Jesus shall return to glorify all who believe in Him (1 John 3:2). Be saved and sure as a believer, if Jesus is your surety!
Jesus has become a surety of a better covenant (Hebrews 7:22). A surety is a guarantee. In Bible days, the word surety was used to describe someone who guaranteed another person's debt would be paid. All of us have a sin debt to God. The good news is Jesus paid it all. Be saved and sure by faith in Christ alone.
There is no way that we can repay our sin debt against God. We have broken God's law. Our conscience testifies as much. The good news is that Jesus paid it all. Believers look to the cross of Jesus, where He died in our place. Our sin debt to God's justice was paid, not in part but the whole. As believers, we are free from a debt that we could never repay, when Jesus is our surety.
In Jesus Christ our Lord be saved and sure, according to God's promises. In the new covenant, God makes four promises to every believer, guaranteed through Jesus Christ (Jeremiah 31:31-34; Hebrews 8:7-13). These promises are: (1) God will put His laws in our mind; (2) God will be our God and we are His people; (3) We will all know the Lord; (4) God will forgive our sins and remember them no more.
