The Lord gave His word to ancient Israel, that if they would cleave strictly to Him and do all His requirements, He would keep them from all the diseases such as He had brought upon the Egyptians; but this promise was given on the condition of obedience. Had the Israelites obeyed the instruction they received, and profited by their advantages, they would have been the world’s object lesson of health and prosperity. The Israelites failed of fulfilling God’s purpose, and thus failed of receiving the blessings that might have been theirs. But in Joseph and Daniel, in Moses and Elijah, and many others, we have noble examples of the results of the true plan of living. Like faithfulness today will produce like results. To us it is written: “Ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of Him who hath called you out of darkness into His marvelous light.” 1 Peter 2:9L.
