For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of His majesty. For He received from God the Father honour and glory, when there came such a voice to Him from the excellent glory, ‘This is my beloved Son, in whom I am well pleased.’ And this voice which came from heaven we heard, when we were with Him in the holy mount. We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.” 2 Peter 1:16-21 (KJV)
It has been said by many people, “You can make the Bible say anything you want it to say.” In one sense that thought is correct if you take a verse of the Bible from one place, out of its context, you can have it tell you to “Go and hang yourself”, but we know that is not what it really says.
If one is to have any understanding of the Scripture it must be understood in the light of other Scripture. “No prophecy of the scripture is of any private interpretation” says Peter, so we must be aware when we interpret Scripture that we twist it by using only that point of interpretation.
Let me give you an Old Testament example. When Moses led the children of Israel through the wilderness to Kadeshbarnea, it appears in Numbers 13:1-3 that there is a direct commandment from the LORD to send men into the Promised Land and come back with report; however in Deuteronomy 1:22 and following we see that there were people of the tribes who had came to Moses requesting that before they cross the Jordan River that spies be sent to examine the land and the people. By knowing that we not only learn that though God may have spoken to Moses directly, He also spoke to him through the people he was leading.
There are many who try to build theologies by using a verse of scripture in one place, one book, one paragraph, or one chapter; and do not look at the whole. If we do not trust and believe the whole for interpretation we will stand in danger of not only losing our minds, but also our hearts to unbelief. The Scriptures are eternal; not one jot or tittle will pass away, until all are fulfilled.
