And the truth shall set you free is one of my favorite scriptures, I quote this often so never to forget to live it!
It is better to tell someone the truth (even if it hurts) or simply yet, do not participate in activities, conversations, or deceit that will need an explanation that may hurt another.
How does one do that? Well, when we engage in conversations or actions, we usually have a gut feeling that what we are doing or about to do does not "feel" right; and at that moment we have a choice, continue down the wrong path that our gut is telling us "danger, Mr. Robinson", (I think I just dated myself with Lost in Space quote), or we can make the bold decision to respond "differently" to the situation at hand and not engage, therefor there is absolutely nothing to "explain" anything that may hurt another.
31 To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples. 32 Then you will know the truth, and the truth will set you free.”
Now, you do not have to follow this simple lifestyle to a peaceful and free life; you can stay on the path you are on, but ask yourself an honest question, how is that working for you in all areas of your life? If it is not "working" try the truth, which always sets one free.
