Love to Man: Saints should be Sincere In

Love must be sincere. Detest what is evil; cling to what is good.

…in purity, knowledge, patience, and kindness; in the Holy Spirit and in sincere love;

I am not giving a command, but I am testing the sincerity of your love through the earnestness of others.

Little children, let us love not in word and speech, but in action and truth.
