They believe if they could just be innovative with music, drama, or church polity, then they'll be more effective and their church will grow. But when our innovation creates widespread disharmony in the church, it hurts the spirit of the church and hinders evangelism. I doubt that God ever blesses a bickering church. It's a dangerous thing to wound or divide the body of Christ. But when there's harmony, the Holy Spirit flows and God blesses the church.
Innovation always has to be weighed in light of the overall impact on the church.
Perhaps there's something you think needs to be done, but others are in complete disagreement with you. Harmony often comes about by relationship. Spend time in relationship with your leaders and congregation. It will always be to the benefit of the work God is doing. One of the keys to advancing the gospel is for the church to be made up of individuals who consider it their task to do the work of the ministry, rather than expecting the paid staff to minister to them.
