543 Only If You Love the Truth Can You Practice the Truth
1 Why is seeking the truth and putting it into practice so very difficult—as though you were rowing a boat against the current, and would drift backward if you stopped rowing forward? It is because humanity’s nature is to betray God. Satan’s nature has taken a dominant role within humans, and this is a reactionary force. Humans with a nature that betrays God are, of course, very liable to do things that betray Him, and positive actions are naturally difficult for them to perform. This is decided entirely by humanity’s nature essence. Once you really understand the truth and begin to love it from within yourself, you will have strength to do things that conform to the truth. This then becomes normal, and even effortless and pleasant, and you feel that doing anything negative would require a great amount of effort. This is because the truth has taken a dominant role in your heart.
2 If you really understand the truth about human life and about what kind of person to be—how to be an aboveboard and straightforward person, an honest person, someone who bears witness for God and serves Him—then you will never again be able to commit evil acts that defy Him, nor will you ever play the role of a false leader, a false worker, or an antichrist. Even if Satan deceives you, or someone evil eggs you on, you will not do it; no matter who tries to coerce you, you still will not act that way. If people gain the truth and the truth becomes their life, they become able to loathe evil and to feel an internal disgust for negative things. It would be difficult for them to commit evil, because their life dispositions have changed and they have been perfected by God.
