Without or with not much of Christ in your life, you try to find happiness on your own. Since we live in an imperfect, sinful world, you encounter obstacles, setbacks, and even make enemies along the way. Then the sorry experiences and hurts you feel start to affect you mentally, making you hate the world and even yourself; you feel like giving up altogether. All I want to say is that you will not find happiness on your own. Then you let Christ into you life and everything changes. Living becomes meaningful. You are now free from the world, as serving him gives you so much joy and satisfaction. Yes, you know exactly where you are going and look forward to that day. The Lord guides you through every moment of your life. And there is much more. The God of Christ is exactly what we sinners need.
