Matthew 24:36

“But about that day and hour no one knows, neither the angels of heaven, nor the Son, but only the Father.”

It is hard to not know something! It’s a relief when we finally discover the cause of an illness. The diagnosis may not be great but at least we know what we are dealing with.
Conversely having knowledge that others don’t have can give us an advantage. Many have claimed to know when Christ will return. Usually to attract attention and followers through their special knowledge. Wikipedia has a great article which lists over 50 of the more popular declarations. Yet none have been right. My guess is that no one ever will be right in setting a date. Only God knows.

However, let me add my own prediction. Christ will come today. Because Christ is always present. Advent is a time for us to prepare ourselves for Christ. Now.
