Conversion is integrated testimony.

We are fully converted when our testimony is no longer compartmentalized from our life, even in part.

At the very front of the new home church manual, the brethren say that the purpose is full conversion.    One less understood part of the gospel is that to change our minds we often need to make physical changes.  Acts of will alone usually don’t do it.  Another way of saying it is that acts of will have to be expressed physically to work.  Just deciding that you are going to start thinking about Jesus during the day is well and good.  But what really works is when you have patterns and habits that draw the gospel into more aspects of your life.  Home Church is part of that.  Physically doing church in your home at some points will make it easier to have a Christian home at others.

Physically eating the bread and drinking the water is necessary to the sacramental changes in our Spirit.  Going through a physical commitment ceremony called marriage is a real commitment.  Mentally deciding to be committed is not.
