Psa. 103:3 who forgives all your iniquity,
who heals all your diseases,
Our Pentecostal fathers used a phrase, ‘double cure’, when talking about the redeeming power in the blood of Jesus. For them, healing and forgiveness were part of the same package purchased by the same price. That is actually the way Jesus connected healing and forgiveness of sin. Remember what Jesus said about the paralyzed man? He said that so you know that the Son of Man has authority to forgive sins, ‘Rise, pick up your pallet and walk’. The rest is history. What about today? Does Jesus heal the sick today? According to the reasoning of Jesus, that is like asking does Jesus forgive sins today. Of course He does. If He forgives sins through the power of His blood then He also heals us from all of our disease. Here are some thoughts from Jack Hayford on today’s verse.
“God’s Saving and Healing Benefit, DIVINE HEALING. This is a definite OT promise of bodily healing based upon the character of Yahweh as the Healer. It is clear that the dimension of healing promised here is specifically to include physical wholeness. The text reinforces the healing covenant, since the Hebrew word tachawloo (diseases) is from the same root (chawlah) as the word for “disease” in Ex. 15:26 (makhaleh). Further, the words for “heal” are the same in both passages (Hebrew rapha’), the distinct meaning involving the idea of mending or curing). These two verses bear witness from the OT that the Lord not only forgives iniquities; He heals our diseases. If under the former covenant bodily healing was pointedly included with the Father’s many other benefits, we can rejoice and rest in faith. The New Covenant “glory” exceeds everything of the Old. If under the former covenant bodily healing was pointedly included with the Father’s many other benefits, we can rejoice and rest in faith. The New Covenant “glory” exceeds everything of the Old, and we can be certain that God, in Christ, has made a complete provision for the well-being of our total person.”
If you think about it, sickness has to be related to sin on some level. Before the fall of man there was no sinfulness and there was no sickness and death. Christ’s death on the cross dealt with the root cause of sickness and death, He died to wash away our sins. If sickness comes from the power of sin then healing flows from the power of redemption. So let’s say with David, ‘Bless the LORD, O my soul, and forget not all his benefits, who forgives all your iniquity, who heals all your diseases…’
