Therefore He is able to save completely those who draw near to God through Him, since He always lives to intercede for them. — Hebrews 7:25

Here's the comfort that holds you steady: Christ not only died for you, He lives for you, making intercession at the right hand of God. There's one mediator between God and men, the man Christ Jesus, and He ever lives to plead your cause. If you sin, you have an Advocate with the Father. Through Him we both have access by one Spirit to the Father. You don't need anyone else to speak for you — the Son holds the floor in heaven on your behalf.
