Despite the wars and rumours of wars, which Jesus predicted, along with natural disasters, persecution, false teaching, backsliding and apostasy, the Gospel still stands as humanity's only answer (Matthew 24:4-14).
That passage concludes: "Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved. And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come."
