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

Christ saves to the uttermost — completely, finally, irreversibly. He's the only way, and he keeps every one of his sheep so they'll never be lost. The one who started this work in you will see it through. Nothing's too hard for him, and he's able to keep you from stumbling and present you faultless before his glory. That's the kind of savior you have.
