Jesus Christ already paid for it !
Isaiah’s prophetic words speak of how Christ’s sacrifice for us would heal us. He writes that by his stripes we are healed and that he has taken our grief and carried our sorrows.
It is important for us to realize that God does not just give a whimsical promise for our healing, without cost. It cost Him terribly. Jesus paid dearly for it, with horrible, excruciating pain, and with His own divine, precious blood. And what He paid so greatly for, He wants us to understand and benefit from. He did it just for us. For you and me! Let His sacrifice not be in vain. Ignoring, denying, or taking lightly His great sacrifice for us is an offense to Him.
