The belief of some people that human history evolves from unconnected events is wrong. The other extreme belief of some that whatever happens is in accordance with the will of God, is also wrong. The truth is that God uses the happenings to fulfil His will. Night and day is the same to God. Night means darkness.
Darkness means rule of satan.
The rule of satan has been upon mankind for several centuries. However when Jesus Christ came into this world as its light, the rule of satan is being removed little by little. Light has come into this world. The children of God who walk in light day and night are present in this world everywhere. However once again spiritual darkness will envelop this world.
