581 Only by Acting With Principles Can One Do Their Duty Well
1 No matter what duty you fulfill, you must always seek to grasp God’s will and understand what His requirements are regarding your duty; only then will you be able to handle matters in a principled way. In performing your duty, you absolutely cannot go by your personal preferences, by just doing whatever you would like to do, whatever you would be happy and comfortable doing, or whatever would make you look good. If you forcibly impose your personal preferences on God or practice them as though they were the truth, observing them as if they were the truth principles, then that is not fulfilling your duty, and performing your duty in this way will not be remembered by God. It is wrong to take what you believe to be correct, good, and beautiful to be the truth.
2 Even though people might sometimes think something is right and that it accords with the truth, that does not necessarily mean that it accords with God’s will. The more people think something is right, the more cautious they should be and the more they should seek the truth to see whether what they are thinking meets God’s requirements. If it runs counter to His requirements, then it is unacceptable even if you think it is right, and it will not necessarily accord with the truth no matter how right you think it is. Your determination of right and wrong must be based solely on God’s words, and no matter how right you think something is, unless there is a basis for it in God’s words, you must discard it. A duty is a commission entrusted by God to people, and it should be fulfilled by acting in accordance with God’s requirements and standards, and by basing your behavior on the truth principles rather than on human subjective desires. In this way, your fulfilling of your duties will be up to standard.
