Some tasks are restricted from you because of a lack of ability. Other tasks are restricted from you because of a lack of qualification or authority. The pride of sin produces the lie that your own efforts can achieve righteousness. The arrogance of sin can convince you that you do not need Jesus. However, the testimony of scripture is that you can never achieve righteousness before God through your own efforts. Salvation comes only through the work of God. Jesus is the perfect high priest who, through His life, death, and resurrection provides forgiveness of sin and access to God to all who believe in faith. 

Hebrews 7 teaches three ways that Jesus, as the perfect son of God, provides for salvation.
