Why do you spend your money for that which is not bread, and your labor for that which does not satisfy? Listen diligently to me, and eat what is good, and delight yourselves in rich food. — Isaiah 55:2, ESV
What are you placing before Jesus that you actually think will be able to do what only Jesus can truly accomplish in you? God has created you to be a worshipper of him—fully devoted and passionately in love with him. Whenever things or others start to crowd him out of that place in your life that he put in you for only himself to fill, you end up trying to find your satisfaction in those things that will never do that.
If you're dating, stop looking to your boyfriend/girlfriend to ultimately fulfill you. Your spouse won't be able to do that either. Not your job, more money, relationships, reputation, food, addictions, entertainment, sports... nothing. You were created for a love affair with God.
When things are out of line, he will come up with the question that is above. Why would we spend money on things that won't satisfy? Why would we labor and work so hard for anything that does not ultimately fulfill? It makes no sense.
I had to check myself today to make sure that nothing was crowding Jesus out of his rightful place. This was my prayer:
Please reveal to me if and hat I try to replace you with to be my true fulfillment. My prayer is still this: all of you and none of me."
What's your prayer?
