“Most current approaches for helping Christians grow to maturity aren’t working. Many church leaders realize something is wrong but don’t know how to correct the problem. A shift may have started, but old traditions persist. Alister McGrath recognizes that we need a better strategy.
Evangelicals have done a superb job of evangelizing people, bringing them to a saving knowledge of Jesus Christ as Savior and Lord, but they are failing to provide believers with approaches to living that keep them going and growing in spiritual relationship with Him… Many start the life of faith with great enthusiasm, only to discover themselves in difficulty shortly afterward. Their high hopes and good intentions seem to fade away. People need support to keep them going when enthusiasm fades. 
I’m convinced that most church leaders are sincere, zealous followers of Christ, committed to helping people grow in Him. They’ve given their lives to Christ and His agenda. The problem doesn’t lie with their passion for God. Instead, it comes from their failure to have a strategic plan that produces maturity and has a practical use in their church.
We need a new approach, a new perspective. Any new approach requires a new way of thinking. And that’s a challenge in itself. It also requires biblical balance because the growth process involves both mystery and method. God’s in charge, but He expects us to do our part.” [From Maturity Matters]
