Jesus is better because Jesus is faithful.
There are many others, like Moses, who have been faithful servants in the house of God. But Christ as a faithful Son built God’s house – which are those who hold fast to Jesus. The faithfulness of Jesus outshines all others.
This is where the letter’s second exhortation and warning are introduced.
“Today, if you will hear His voice, do not harden your hearts…”
A heart becomes hard – stubborn and obstinate – through the seduction and delusion of sin. A hard heart rebels. A hard heart is unwilling. A hard heart refuses. A hard heart opposes. A hard heart produces unbelief, not faithfulness. A hard heart does not enter His house. A hard heart does not enter His rest.
Today, right now, choose to hear and obey His voice.
