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!

Surely you could add something...
