For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. 2 Peter 2:21
Remember, 2nd Peter is primarily a warning to us concerning false teachers and in verses 18-22 Peter provides us with one of the greatest dangers of following false teachers. This danger is their control over your life that you, as a true Christian, may not be able to return from. Verse 19 says, “While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage.” This person teaches “liberty” that is in opposition to God (but he sounds good), and instead of liberty he leads you to bondage. You become a slave to sin again!
Peter is not saying that we lose our salvation, for he warned in 2 Peter chapter 1, that even if we are saved yet not walking and growing with God then we will soon act as if we are not saved and even forget. What Peter is saying is this. Knowledge is responsibility! Once we know the truth we are responsible for we do with it. That’s why he gives us verse 21, “For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.“
In Matthew 11:24 Jesus told those in Capernaum, “it shall be more tolerable for the land of Sodom in the day of judgment, than for thee.” Why? Because Capernaum had been given more truth, more knowledge and had seen more works of Jesus Christ than Sodom. Again, with knowledge comes more responsibility. When we purposely refuse to act on and obey the knowledge we have been given, Peter says, “the latter end is worse with them than the beginning,” (verse 21). It becomes harder and harder to come back. Before I was saved, I unknowingly sinned many times for it was natural. Now I know better, but if I still choose to sin—it becomes purposeful rebellion against God. The drug addict gets saved, obeys God and lives a sober life. But if he slips back into the old lifestyle—you may never see him again. It will be much harder for him to come back a second time. He has chosen to rebel against the truth of God’s Word and he knows it.
Let’s bring this close to home. The Christian who knows to witness to the lost and does not do it, it becomes easier and easier to not witness. The Christian who refuses to give, it becomes easier and easier to not give. The Christian who refuses to minister to others, read his Bible or pray, it becomes easier and easier to sin—even to the point of no return!
