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.

Apparently, Tim Keller, the well known preacher and author who died recently, would repeatedly remind his team that it is the gospel that truly changes everything.

‘My sin, O the bliss of this glorious thought;

My sin, not in part but the whole,

Is nailed to His Cross, and I bear it no more,

Praise the Lord, praise the Lord, o my soul.

It is well with my soul…’

…and it is all because of Jesus.

Note that verse 15 begins with the words: ‘For this reason…’ It causes us to look back. In the previous verses (11-14) the writer has described the perfection of Christ’s offering of Himself – of His own blood; He has spoken about its superiority to all that came before in the Jewish system. His sacrifice can bring cleansing to the inside of a person, and not just the outside. This is good news for all who come to Jesus for eternal redemption (v.12).

This gospel really does change everything.
