If people believe in God but do not pursue the truth, and never focus on practicing the truth, then they could believe for years without experiencing any change. Without the truth, life is empty. If people have some knowledge of God, know how to live a meaningful life, and can do some things to satisfy God, then they will feel that this is real life, that only by living in this way will their lives have meaning, and that they have to live this way in order to bring satisfaction to God, repay God, and feel at ease.

II

If they can consciously satisfy God, put the truth into practice, rebel against themselves, abandon their own ideas, and be submissive and considerate toward God's intentions—if they're able to do all these things consciously—then this is what it means to accurately put the truth into practice, and to genuinely practice the truth. It's not like before, merely relying on imaginings and following regulations, and thinking that this is practicing the truth.

III

Relying on imaginings and following regulations is very tiring, not understanding the truth and doing things without principles is also very tiring, and blindly doing things without goals is even more tiring. When you understand the truth, you won't be constrained by any people, events, or things, and you will truly have freedom and release. You will act in a principled way, and be relaxed and happy, and you won't feel that this causes too much suffering. If you have this kind of state, you have the truth and humanity, and you are someone whose disposition has changed.
