The Godless civilization can be destroyed at any moment.
Since the creation of the material world, there have been two kinds of men–the devas and the asuras. The devas are always faithful to the Supreme Personality of Godhead, whereas the asuras are always atheists who defy the supremacy of the Lord. At the present moment, throughout the entire world, the atheists are extremely numerous. They are trying to prove that there is no God and that everything takes place due to combinations and permutations of material elements. Thus the material world is becoming more and more godless, and consequently everything is in a disturbed condition. If this continues, the Supreme personality of Godhead will certainly take action, as He did in the case of Hiranyakasipu. Within a second, Hiranyakasipu and his followers were destroyed, and similarly if this godless civilization continues, it will be destroyed in a second, simply by the movement of one finger of the Supreme Personality of Godhead. The demons should therefore be careful and curtail their godless civilization. They should take advantage of the Krishna consciousness movement and become faithful to the Supreme Personality of Godhead; otherwise they are doomed. As Hiranyakasipu was killed in a second, the godless civilization can be destroyed at any moment.
