We can not deny modern man is governed by time or clock.Work schedule, school schedule, appointment times, airplane arrival and deparure times, etc. Time is very important to us. Without time we will be uncoordinated.Even the sun, stars and the moons, planets, move at precise times.
In the Bible, it is written in the fulness of time Jesus was revealed to the world in human form. Jesus who the Bible revealed as God stepped out of eternity to save or redeem man. He sacrificed Himself to save us from our sins. To His followers, He left us the assignment to tell the good news to the world and said He will return this time like a thief or at the time known only to God the Father.
For Christians we are told thru the Bible to be ready, watch , and pray and obey His commandments.
Speaking of time, let me invite you to read Psalm 90.
