God the Father created the heart of man to hunger thirst adore and yearn for Himself. Until the heart does what it was created to do, it will be on an endless struggle to find it. But when it finally does find it's place of rest and belonging~nothing else will ever do.
The heart that belongs to it's Creator will no longer be obsessed with sports, entertainment, shopping, money, drugs, alcohol, sex, politics, and other worldly idols. It just won't! How can it when it's found it's niche; that perfect fit it's been longing for its entire life? It would be like a lawnmower being used for a floatation device or an automobile until one day it's used to cut grass and it feels right! It works so much better than all those years laboring at what it wasn't created to do!!
Jesus says we can't serve one (worldliness) without hating the other (GOD) He created our hearts so He knows! Our Father created our hearts with an intense need to worship and adore and He wants it to be HIM not our idols. This is one of the first things God teaches His children! Separation from worldliness. Luke 16:13
I believe this is what Jesus means when He says return to your first love. Rev. 2:4 We were created from His heart to be one with His heart and somehow (satan/sin) we got distracted and went searching all around for the key to unlock this love (God) and peace in our hearts. There is only one perfect key that will fit and His name is JESUS~
