WHY DON'T CHRISTIANS BELIEVE JESUS ?........

Why don't Christians believe Jesus when He reveals THE EXACT MONTH of the year in which THE RESURRECTION & RAPTURE of His Elect Body of Christ Church  will take place ? In the following Scriptures Jesus uses a metaphor to compare His Church to a field crop of grain in Israel. The particular grain crop He is comparing His Church to appears "white" in the field when it is ready to harvest. 

Barley is the only grain crop that appears "white" in the field when it is ready for harvest, in Israel, during the Spring MONTH OF NISAN  on God's Sacred Calendar. It is the month of April on the Gregorian Calendar. 

In the following Scriptures Jesus refers to Himself as, "He that reaps", and He also refers to the resurrection & rapture of His Church into heaven as, "gathers fruit unto life eternal".  Jesus states that THE TIME OF THE YEAR  for the resurrection & rapture of His Elect Church is when the "fields are white already to harvest" in THE SPRING MONTH OF NISAN according to :

John 4:34-37 ( Jesus speaking )

"My meat is to DO THE WILL OF HIM that sent Me, and to FINISH HIS WORK. Say not ye, There are YET FOUR MONTHS , and then comes the harvest ? Behold, I say unto you, Lift up your eyes, and look on the fields for THEY ARE WHITE ALREADY TO HARVEST. And HE THAT REAPS receives wages , and GATHERS FRUIT UNTO LIFE ETERNAL ; that both He that sows, and He that reaps may rejoice together."

SO, THERE YOU HAVE IT:

Jesus has revealed to us that the resurrection & rapture of His Elect Body of Christ Church will happen ONLY in the Spring MONTH OF NISAN , which is also April, when the Barley fields in Israel "ARE WHITE ALREADY TO HARVEST'.........  NOT FOUR MONTHS LATER IN THE FALL OF THE YEAR.    Why don't Christians take Jesus at His Word ?

According to Your Holy Word, come Lord Jesus !
