"For as the lightning flashes and lights up the sky, so will the Son of man be in his day"

Scripture: Luke 17:20-25
What can lightning tell us about the coming of the Lord and his kingdom? The Jews is Jesus' time were watching in great anticipation for some sign which would indicate when the Messiah would appear to establish the kingdom of God. The Pharisees' question on this matter was intended to test Jesus since they did not accept him as the Messiah. Jesus surprised them with the answer that the kingdom or reign of God was already here! Jesus spoke of the coming of God's kingdom as both a present event and an event which would be manifested at the end of time. The "Day of the Lord" was understood in the Old Testament as the time when God would manifest his glory and power and overthrow the enemies of his people, Israel.Jesus identified himself with the "Day of the Lord". "Son of man" was understood as a Messianic title for the one who would come not only to establish God's kingdom but who would come as Judge of the living as well as the dead. Jesus points to his second coming when he will return to complete the work of restoration and final judgment. While we do not know the time of his return, we will not mistake it when it happens. It will be apparent to all, both believers and non-believers as well. When the Pharisees asked Jesus what sign would indicate the "Day of the Lord", Jesus replied that only one sign would point to that day and that sign was Jesus himself. Jesus surprised the Jews of his time by announcing that God's kingdom was already present among them in his very person.
