This man refused to take a Rosary because he said the Catholic Church was a greedy organization that didn’t help anyone. Steve told him that nothing could be further from the truth, especially since the Catholic Church was the largest charitable organization in the world. This led to a conversation about faith. This man was living a very worldly life and didn’t see the need to change.
Steve shared his own conversion story about how he used to live that very lifestyle and then explained that worldly pleasures will only satisfy you temporarily and that such sin will often lead to ruin. This man tried to argue that it was impossible to live an upright and chaste life, but Steve gave many examples of people he knew who did just that and how their Catholic faith truly satisfied their deepest desires.
It all comes down to faith in God. Do we really believe in Him? If so, then we can live chastely. Surely He who asks us to do so can make us capable of it!
