Jesus Christ will return the second time at a time that is unknown to man; His return is described by Jesus Himself as unexpected as a thief in the night. Therefore, the admonition for the disciples of Christ are to be watchful and vigilant for the second coming of Jesus Christ, because we do not know when He will actually return. The understanding that Jesus can return at any moment should compel us to live godly and holy lives so we will not be ashamed when he returns.
