Why is seeking the truth and practicing the truth so difficult— as though you were rowing a boat against the current, and would drift backward if you stopped rowing forward? And yet, why is it actually much easier to do evil or meaningless things— as easy as taking a boat downstream? It is because humanity's nature is to betray God. Satan's nature has taken a dominant role within humans, and this is an antagonistic 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. It's decided entirely by humanity's nature essence.

Once you really understand the truth and begin to love it from within yourself, you'll find it easy to do things that conform to the truth. You'll do your duty and practice the truth normally— you'll even do them easily and joyously, and you will feel doing negative things would require a great amount of effort. This is because the truth has taken a dominant role in your heart. If you really understand the truths about human life, then you will have a path to follow in regard to what kind of person to be, how to be an aboveboard and straightforward person, an honest person, and someone who bears witness for God and serves Him.

Once you understand these truths, 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 misleads 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 will become able to hate 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.
