You could compare your spiritual life to a balloon. You could also compare the church to a balloon. My boys love them and fight over them when we go somewhere that has balloons, like restaurants. They like balloons that have regular air in them, but they LOVE the ones with helium. They float. The ones with air just fall.
There is a dangerous tendency to assume that our spirituality has to always be floating, that we need to be soaring on wings like eagles, living on the mountaintop, staying fired up for God…insert any Christian cliche here that will suffice. You get the picture. I even received an email from a youth pastor recently who asked me what advice I could give him to help keep his kids on fire for Jesus. His heart was pure, but his perspective was wrong. I had no advice for him but to scrap the whole idea of being fired up and replace it with abiding in Christ, walking in the Spirit, and living by faith in the gospel.
