Christ's Covenant is Eternal Life

Hebrews 9:15 For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant. Christ through His death and resurrection, every legal hindrance has been met and satisfied. There is nothing that can keep me from assurance except my own faith. Its not about thinking our way into salvation or to reason our way into salvation. The only way to get in is to believe Him with my heart which is sealed by the Holy Spirit. We must be clear of Christ's Covenant is Eternal Life.
