Christianity is about change. We are born again of God's Spirit as a new creation. We then, by God's grace, pursue spiritual change and transformation. But for most of us, that change feels like a monumental task. First, it's so difficult to believe we're now something different. Our doubt and insecurity prevents our change. Second, we often fail as often as we succeed. So it's difficult to live out this change promised to us in Scripture.
But the key to spiritual transformation isn't a manic focus on self-improvement or always making the right choices. The foundation of our faith isn't moral, it's believing in the power of miracles. It's believing that only God can change us, and while we are active participants, God must do more than simply shift our motives or thinking. He must raise us from the dead.
While you may look forward to heaven and the promise of future resurrection, part of the good news of Christianity is that your resurrection begins now.
