Andrew Strom has announced that he is leaving the "Out of Church Movement". I have some sympathy.
A big part of the problem is that it is easier to sit round and criticise the established church, than to get out and build something better. A workable strategy for those who want to go forward and build the body of Christ is not as popular as a critique of the church. The flaws of the church, justify our inactivity. Throwing stones is easier than building a glass house (that the world can see into).
Being "Out of church" is a backward looking position. It describes who you are not, not who you are. . You cannot get to where you are going, by continuing to look back at what you have left. You cannot get to where your destination, by knowing where you want to leave. The only way to get to where you are meant to be is to find a good map and get on the road and follow it.
Those who are dissatisfied should stop looking back at what they have left, and get into something better. If something better does not exist, then get a godly strategy and establish something that will glorify God. If you don't know how to do it, ask someone who does. There are plenty of good maps available.
The body of Christ will not be built by looking backwards. It will only be built doing the hard stuff and moving forward into the Lord's new thing.
