Jeremiah 1:5-9 - I appointed you as a prophet to the nations. I have put My words in your mouth.
“Thus says the Lord” and “the word of the Lord came to . . .” is the result of exactly this process.
So inspired were the prophets that their words were identified as the very words of God. God uses our language and our means of communicating to reveal to us, His character. Be it lineage, poetry, prophecy, parable, God has communicated to us as He desired.
The Bible says that we are to submit to it as to the very words of God. We come to the Bible with reverence and submission. Claiming that the Bible is not the inspired Word of God is to stand in opposition to God Himself. The mystery of inspiration is just one of the mysteries surrounding a Supreme Being and His dealings with us. Not understanding inspiration, however, should not keep us from adhering to it. Ephesians 1:11 tells us, that “In Him we were also chosen, having been predestined according to the plan of Him who works out everything in conformity with the purpose of His will . . .” If we simply live out our lives in conformity to that fact, we encounter surprisingly few problems regarding the authority of God’s Word.
