The book of Hebrews was written to make this one point — the New covenant is better than the Old in every way.
The reason is simple. The New Covenant totally rests on the shoulders of Jesus.
His once for all sacrifice.
His eternal priesthood.
His indestructible life.
As Hebrews 7:22 states, “This makes Jesus the guarantor of a better covenant.”
His finished work on the cross guarantees every promise, every provision.
His resurrected life in you guarantees that every promise, every provision of the New Covenant becomes a reality in your life.
No longer do you have to rely on human effort. you can trust the one who loved you and gave himself for you.
So what makes the New Covenant better than the Old?
In a word — Jesus.
