Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.

This is the first and great commandment.
And the second is like unto it, Thou shalt love thy neighbour as thyself.

No power or influence can or ought to be maintained by virtue of the priesthood, only by persuasion, by long-suffering, by gentleness and meekness, and by love unfeigned;

COMMENTARY

Strive not about words to no profit
When you find yourself needing to express a moral conviction to someone else, what is your motivation behind doing that? To get them to change their behavior for your benefit? To get what you want from them? Because if so, then you are not testifying of truth, you are having an argument or a debate. And in some circles argument and debate might be fitting, such as in academia, but as this verse makes clear they are of no use when testifying of the truth. Ultimately, when we are trying to influence the religious perspective of another person it should never be motivated by a desire to receive something from them.

Thou shalt love thy neighbour as thyself
The motivation for expressing our moral convictions and exercising an influence over another person should only ever be one of love. Rather than asking them to change for our own benefit, we should be inviting them to change for their own benefit. We should be making our case because we care for them and truly believe that their lives will be happier with this piece of enlightenment.
Recall the example of Daniel that we just examined. He was petitioning the prince of the eunuchs to let him eat a diet that conformed to his religious convictions, but he only made any headway when he illustrated how this approach was also going to help the prince of the eunuchs get what he wanted as well. When those we teach can feel that we sincerely seek their own good, and are not just trying to mold the world to our own preferences, they are far more likely to care about what we say.

Influence ought to be maintained only by love unfeigned
But remember that our display of care and concern for the person we speak with must be “unfeigned.” We must not pretend to care for someone just to coerce them into doing what we want. The account of Daniel also made clear that the compassion between him and the guards was sincere.
So do change those around you, but only do it because you sincerely love them and just want to help them.
