I believe that one of the reasons that God created human freewill was so that faith and love would exist within us. He loves us enough to allow us to choose whether or not to follow him. So, while our broken world is full of hurt, love does exist and it carries the most incredible and overwhelming power. True love manifests itself in us in ways that can be quite surprising. Who among us hasn't been surprised by what people are willing to sacrifice for someone for whom they have deep adoring affection? Thus, Jesus said that those who truly believe in him will lose their life for his sake; they place his interests before their own. They end up seeking to glorify him in how they live. Paul called this "being a living sacrifice"
Some people picture Christians as self-loathing religious rule-followers. They think that we live in a state of shame and guilt subjected to oppressive rules and regulations of a controlling church. Some churchgoers have an equally distorted image of what it means to follow Christ believing that merely repeating a particular prayer, kneeling before an altar, or robotically following a set of rules (Jesus called this last group "whitewashed tombs") will lead to a fulfilled life with Christ. Unfortunately, disappointment follows this approach when their spiritual walk is short-lived and empty. They find that a formulaic approach to God is a dead-end road leaving them further from God rather than closer.
When true belief is found, the disciple approaches God in a manner that can be somewhat similar to other relationships in their lives. A follower feels compelled to learn as much as possible about the incredible one with whom this relationship has started. The more we understand him, the more we grow to appreciate how truly magnificent God is. The more we appreciate him, the closer we grow in our relationship with him. We also see that while we can never fully understand God, we are called to trust him. To trust in the unseen and to believe his promises. This is where our faith lies.
