And [God] said, “If you diligently heed the voice of the Lord your God and do what is right in His sight, give ear to His commandments and keep all His statutes, I will put none of the diseases on you which I have brought on the Egyptians. For I am the Lord who heals you” . . . “So you shall serve the Lord your God, and He will bless your bread and your water. And I will take sickness away from the midst of you. 26 No one shall suffer miscarriage or be barren in your land; I will fulfill the number of your days. Exodus 15:26; 23:25-26 NKJV
When God delivered Israel from the bondage of Egypt, He revealed Himself to them as Jehovah Rapha—the Lord that heals you—the One who cures, repairs, and makes whole. He promised not to bring sickness on His people, and if sickness came, He further promised to take it away if they “served the Lord” i.e., worshipped Him and did the work of the Lord.
Even if sickness came, God’s promise was two-fold: (1) He would take the sickness away, and (2) fulfill the number of your days. Sickness and disease don’t determine how long you live—but God! Jehovah Rapha gives you victory over sickness to fulfill the number of your preordained days. Man’s life span has increasingly shorten since Adam’s fall except for Methuselah who lived 969 years. Adam lived for 930 years; Moses lived for 120 years; David lived for 70 years; Jesus lived on earth 33 years; and, Paul lived for 66 years. In each case, God fulfilled the number of their days.
Is it always Jehovah Rapha’s will to manifest healing? Well, it certainly was for the man born blind (John 9:1-3). But Paul left his disciple, Trophimus, sick at Miletus (2 Tim. 4:20); and Paul himself lived with a painful infirmity that he described as a “thorn in the flesh” (2 Cor. 12:7-10). God manifested healing, as an act of mercy, when another disciple of Paul, Epaphroditus, was sick unto death (Phil 2:25-27). So, is it always God’s (Jehovah Rapha) will to manifest healing? Yes, healing is Jehovah Rapha’s nature and what He promised (Ps. 107:20), but if it seems not, it’s only because He has something better!
