Paul was letting us know that it would happen in an instant and few would even notice. He was speaking, of course, of the last trumpet, the coming of the Lord with His host of holy ones, the coming of the kingdom of God, establishment of the kingdom of heaven, the dawn of the day of the Lord, the fulfillment of the new covenant – that day of all days when the time of Israel will have been fulfilled and God’s Messiah would rule over all the nations.
Precisely when is the moment that night turns into day? Only God can know because it happens in the twinkling of an eye. Yet in that instant of which Paul wrote, the night of Adam became the day of Christ. The night of Satan’s dominion became the day of Christ’s kingdom. The night of stars in a dark sky became the day of the sun of righteousness – Jesus Christ our Lord. From that instant, He became not just the King of the Jews, and not just the head of the church, but the King and Head of every single human being. Every single one.
In that twinking of an eye, everyone was born again. God gave a new heart to every person in the human race, for all generations to come (Jer 31:31-34; Heb 8:8-12). From that instant forward, God would be judging the secrets of men through Christ Jesus (Rom 2:16). That moment was rapidly approaching in the waning days of the apostles. The book of Hebrews says that what was obsolete and able to be shaken was about to be discarded (Heb 8:13; Heb 12:27) and with this the words of the prophet(Hag 2:6), the psalmist (Ps 102:26), and even the Lord Himself (Mark 13:25) agree. So much happened in that instant!
It happened sometime in the late 1st Century A.D., invisible to human eyes but perceptible to pure human hearts. This was according to the timetable that the Lord, His prophets, and His apostles had laid down. That was the dawn and we have been living in the day of Christ ever since.
Oh, yes – and the eye that twinkled was God’s.
