Here’s what I am thinking about this morning. 

Mark 4: 9 Then Jesus said, “He who has ears to hear, let him hear.”  LINK to source

Revelation 2: 7 He who has an ear, let him hear what the Spirit says to the churches. To the one who overcomes, I will grant the right to eat from the tree of life in the Paradise of God.  LINK to source 

Here in Revelation 2 was not the first time John had heard JESUS say ‘he who has an ear let him hear.’
Does your sanctified imagination run like mine, wondering about the Apostles, hearing what JESUS said with their physical ears, and then, after He was gone back to Heaven, picturing Him in their minds and hearing the words He said again? I wonder if when John was on the Isle of Patmos and heard those words again, did he smile and think, ” I’ve heard You say that before. I wonder did hearing those words again give him even more confirmation that he was indeed speaking with The LORD JESUS. 
This I am not wondering about, I am fully confident that YESHUA was the best student ever! He studied Scripture from childhood and used it for strength, wisdom, and guidance all His earthly life as The GODMAN.  Who are we to not follow His Lead and study to show ourselves approved?  (2 Timothy 2:15)

Good morning, my Friends  ~~~ Holy hugs, Kathie
