I couldn’t miss it in Mark 13!
“Take heed lest any man deceive you” (5).
“But take heed to yourselves” (9).
“But take ye heed: behold, I have foretold you” (23).
“Take ye heed, watch and pray: for ye know not when the time is” (33).
“Watch ye therefore: for ye know not when the master of the house cometh…Lest coming suddenly he find you sleeping.” (35, 36).
“And what I say unto you I say unto all, Watch” (37).
Mark, beware what and whom you listen to!
Mark, be careful how you live!
Mark, pay attention to God!
Mark, live for Him!
