In verse 32 Jesus said, “But of that day and hour no one knows, not even the angels in heaven, nor the Son, but only the Father.” We don’t know the day or the hour, but we should be able to see the signs and perceive the season. Instead of trying to figure out exactly when He will return, Jesus said that we should always be ready: “Take heed, watch and pray; for you do not know when the time is.”
