Our Merciful Priest (Hebrews 2:14-16)

If Christ merely pays our debt for today then we are still in trouble. This would mean that our sins are only covered until today. It is true that God is merciful if he does this, but God does more than merely take a few sins away. God takes all our sins away and restores us to a right relationship with him. In fact, we have a priest who is better than the priests in the Old Testament. How can we have a priest today who is better than the priests of the Old Testament? Those priests were tangible and could look us in the eye. So, why is Christ a greater and more merciful priest?
