They want answers to life's ultimate questions. They are looking for God and a relationship with God so they can order their lives accordingly. And that's fair. But people don't always stop there. That isn't going to happen.
Nothing works that way.
Scott Peck wrote a well-known book called A Road Less Traveled. Life is difficult, and the Christian faith never promises it will deliver a life free of such difficulty. The Bible teaches that when you give your life to Christ, your eternal destiny is altered, you experience a radical reorientation of your priorities, you find a new purpose in life, and you encounter the power and work of God in your life. But these experiences are far different from the instant removal of every problem, every struggle, or every issue of pain. Christians believe that the Bible says God can and does do miraculous, incredible things when you are in relationship with Him, but that's not what you should look for, or what God always promises to deliver.
