God moves at levels we have very little understanding of. We have two lovely and intelligent dogs but they have no idea what I do when I go to work. In fact they have no concept of what my work is nor even that there is such a thing as work. All they are aware of is that I’m around sometimes and sometimes I am not.
God likens us to sheep and Him as a Shepherd. We really have no concept of His work.
It is good to keep this in mind when we pray about or consider the Church. Sometimes the local church we are part of can loom too large in our minds as if it was all that God is doing in our area or land. Thank God for faithful men and women who follow God and are led to work with Him to build His Church. And thank God if you are benefitting from the service of such men and women.
But God is doing something bigger. Don’t become tribal or sectarian or worried if people don’t stay. Often they are God’s servants doing what God wants them to do. And if not, God is still building His Church and nothing the devil or men do will stop that.
Just make sure you are where God wants you to be, doing what He wants you to do.
