"A SHADOW OF THINGS TO COME".............

"Things to come" is speaking of the prophecies of future events yet to be fulfilled. "A shadow" is speaking of a direct connection between the timing of  two separate future prophetic events occurring at the same time.

The two greatest prophetic events yet to be fulfilled, in the future, are the rapture of the Body of Christ Church and the Second Advent of our Lord Jesus Christ in that order.  

The following Scripture is the single most informative Scripture concerning the timing of these two separate future events, and was revealed by Jesus Himself,  only to the Apostle Paul who is  the only designated post-crucifixion apostle and prophet to the Gentiles. It is important to keep in mind that Jesus revealed this information to Paul AFTER He was crucified and resurrected to heaven. Jesus did not reveal this information to His original disciples so it does NOT appear in the four gospels of Matthew, Mark, Luke, and John. The Scripture which states, "But of that day and hour knoweth no man..." is found in the four gospels which were given to them BEFORE the crucifixion and resurrection of the Lord Jesus. Many things changed from BEFORE the crucifixion and resurrection to AFTER the crucifixion and resurrection including: 

The Covenant of the Law was changed to the Covenant of Grace. 

Jesus was the Messiah to the Jews only was changed to Jesus being the Messiah also to the Gentiles.

Many things were also revealed to the Apostle Paul post-crucifixion which were not previously known such as the rapture of the Church.

The revelation of when to expect  "that day" to happen was also revealed post-crucifixion in the Gospel of the Apostle Paul  as follows :

Colossians 2:16-17

"In respect of a holyday, or of the new moon, or of the Sabbath days which are a shadow of things to come; but the body is of Christ."

Jesus revealed the foregoing Scripture to the Apostle Paul to show His Church when the coming prophetic events would happen. Jesus says that there are only three days during the year on which prophecies will be fulfilled:

(1)  on "a holyday" which is one of the seven feasts days of the Lord of which four were already fulfilled at the time this Scripture was given to Paul leaving the three fall feast days beginning with the Feast of Trumpets which always falls on the new moon of Tishri 1. 

(2)  on "the new moon" day which comes twelve times a year on the first day of God's sacred lunar calendar. 

(3) on "the Sabbath" days which come once a week on the seventh day of each week fifty -two times a year.

Therefore for anyone to say that the rapture can happen at anytime or on any day without warning is  NOT telling the Truth of the Scriptures.

2 Timothy 2:15

"STUDY to show thyself approved unto God, a workman that need NOT TO BE ASHAMED."

According to Your Word, come Lord Jesus !
