I had a place here I wanted to show you, the first place of this Scofield here, what he wrote in a footnote here. I believe it's found in Romans the 3rd chapter. He said here, as he interpreted it through Webster, of course, in the footnotes. He said, "Sin is rejecting the revealed will of God."
Sin in its initial form is to reject the revealed Word of God, or will of God. When God has revealed something as His will, and to reject that is to blaspheme, or to reject God.
What was the first sin? Let's look at it. You go back here in Genesis 3. You may read it when you get home if you want to. Genesis 3, when God put the garden of Eden, put Adam and Eve in there, He told them things that they (That was His Word.)--that they could do, and things they could not do. Now, watch when Satan come to Eve, he said "God hath said, 'Thou shall not eat thereof,' but surely thou shall not die." See it? Then Eve wilfully... You get it? Eve wilfully doing something that she knew God said not to do. Is that right? Now, look at it. When Eve wilfully... The first sin that was ever committed (Is that right?), Eve, wilfully knowing the will of God and refused to do it. Is that right? That's the first sin.

Then what is sin? In Saint John the 3rd chapter, the 18th verse, Jesus Christ said, Himself, is this, that, "He that believeth not is condemned already." Is that right? Then "sin" is actually "unbelief."
Satan in his enticement told Eve that God said that, but He didn't mean it. See how he whitewashed the Word? Well, now he said, "Now, God said It, but He didn't mean It." In other words, "Our eyes will be opened. You'll know, know a lot more knowledge."
And now, that same rotten lie is told by Satan to preachers and church members today, to say, "The Word of God says so-and-so, but It don't mean that." God's Word means just exactly what It said. That's right.
