Yet contemporary evangelism often seems to depend on the world. A felt-needs approach to worship assumes that the world understands its problem, its truest, deepest needs. All we need to do is somehow show that Jesus is the answer. Evangelism begins when we have shown non-Christians that their felt needs are at best symptoms of the real problem they haven't yet faced. At its heart, the way we worship is shaped by what we really believe.
Worship is the ritual reenactment of our theology.
If in our worship people are not confronted with God's judgment and grace, any seeming success in evangelism is actually failure, and we have only made genuine evangelism more difficult. The churches in which many of our congregation's members were raised saw evangelism chiefly as getting people to step across the line, to make a decision, to surrender all by rededicating their lives. As they have found a home in the Reformed family, they've been refreshed by the marvelous biblical truth that evangelism is not just for unbelievers, but for believers also. The process of being evangelized is never ending, because we are always simultaneously justified and sinful, believers who yet struggle with doubt. These are questions that the most mature Christian asks every week.
