What does it mean to let love be without dissimulation?
Dissimulation means hypocrisy. Letting love be without dissimulation means love must be sincere and not faked. It means not exercising your gift only with the wealthy and more cultured people, but being ready to exercise it toward those of low esteem as well. Love is the core of Christianity.
Les explains that love is the very core of Christianity, and he warns not to skim over the big word “dissimulation.” He says if you do not know what it means, look it up. The meaning is: do not be hypocritical. Do not exercise your gift only with the wealthy and the more cultured people; you must be ready to do it with those of low esteem. This follows his discussion of gifts such as exhortation, giving, ruling, and showing mercy with cheerfulness, where not everyone has the same ability but each should use his gift and give God the credit.
