Not much to interpret or figure out here! Jesus is very plain: Put things in the proper perspective! Fear the things that can really harm you. Know the enemy. Know those on your side. Don't believe fake news!
In a day and age when anyone can say anything and believe anything, there is still only One Who is Truth! Don't believe fake news! He says His children are valuable to Him. He says He will protect us (Psalm 91:1-2). So then, why do we follow the dictates of this world? Why do we live as if we do not know Him?
Again, Jesus is very plain: deny Him (by our actions and words) and He will deny us! (Matthew 28:33) Our actions reveal who and whose we are! It cannot get any plainer, any simpler, and more basic than that!
