When speaking of the last days, Christ said "Because iniquity shall abound, the love of many shall wax cold. But he that remaineth steadfast and is not overcome, the same shall be saved."
Iniquity abounds, but we shouldn't get so caught up in being disgusted with it that our love stagnates. Becoming embittered over the state of the world, community, and so forth is a snare of the adversary. He would have us focus on the evil so our love will "wax cold" and we become ineffective servants. While we must fight against evil, our love and appreciation for the good can be paramount in our lives.
