" The enemy can use against you anything you feel you “have to have” to be happy. If you think you have to be married to be happy, the enemy can use that against you. If you think your boss has to change before you can enjoy your work, you’ll go year after year dreading it, thinking that’s why you can’t be happy.
It’s good to have hopes and dreams. It’s good to wake up each day believing and expecting. But don’t wait for those things to come before you enjoy your life and find happiness. This is the day the Lord has made, not tomorrow, not when all your dreams come to pass, not when all the negative people are changed, but today.
Understand, God has you exactly where he wants you. If you’ll learn to be happy where you are, God will take you where you want to be. He’s promised He will give you the desires of your heart. If there is something you really want, I would encourage you to put it on the altar. Just say, “God, I would really love to have this. God, You know the desire You put in me. I would love to be married. I’d love to see my spouse change. I would love to be promoted. But God, I’m not waiting on that to be happy. I’m happy right where You have me.”
That’s the kind of attitude God is looking for. "
