(From Pastor Johnson's sermon)
If there is absolute moral truth then it has to come from God himself.
And that means that all of the Bible has to come from God himself.
Thousands upon thousands of so-called Christians believe that a good part of the bible is the invention of human writers.
Dr. Martin Luther says in his large catechism: "We know that God does not lie. I and my neighbor, in fact, all men, may err and deceive, but the Word of God cannot lie."
2 Peter 1: 20 (New American Standard) But know this first of all, that no prophecy of Scripture is a matter of one's own interpretation,
21 for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God
2 Timothy 3: 16, 4: 3,4 All Scripture is inspired by God...For the time will come when they will not endure sound doctrine; but wanting to have their ears tickled, they will accumulate for themselves teachers in accordance to their own desires,and will turn away their ears from the truth and will turn aside to myths.
