2nd Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, thoroughly furnished unto all good works.
Even though God-ordained prophets speak on God’s behalf, they are finite, and therefore they might not be 100% correct every single time without fail. Even those prophets who were fully loaded with The Holy Spirit in some instances made mistakes, and in some cases, they did not fully understand what they were prophesying. That does not make them inauthentic, for if we go that route, we will end up throwing the proverbial baby out, with the bath water.
Light, and truth are progressive, and in some instances, it takes time for the prophet to hear, and understand the voice of God clearly. In some instances, the rays of light once shed upon the prophet’s mind in years gone by are superseded by additional truth, so yes, the prophets of God can in rare instances, can say or write things which may seem to be a mistake from the finite perspective.
For instance, Paul writes that bodily exercise profits little, but Ellen G. White is inspired by the same God of heaven, many centuries later to inform folks that physical exercise is a huge deal, and it is critically important, not only for good health, and longevity, but also for staving off many diseases and ailments which now afflict the human family.
1st Timothy 4: 8 For bodily exercise profits little: but godliness is profitable unto all things having promise of the life that now is, and of that which is to come.
May God add His blessing to the study of His word. “Good night” and God bless!
