The dangers of the assessments of arrival greets everyone in ministry. The danger that you would quit thinking of yourself as being in a different category from those to whom you minister is right around the corner. This danger greets you every day because there are carnival mirrors all around that have the power to give you a distorted view of yourself. And when you think you’ve arrived, when you quit being convicted of and broken by your own weakness, failures, and sins, you will begin to make bad personal and ministry choices. The reality and confession of personal spiritual weakness is not a grave danger to your ministry. God has chosen to build his church through the instrumentality of bent and broken tools. It is your delusions of strength that will get you in trouble and cause you to form a ministry that is less than Christ-centered and gospel-driven.
