Not everyone is a missionary.
Ephesians 4 identifies roles in the church. My thoughts on roles:
We say "every member a missionary" but we don't actually mean it. What we really mean:
But "missionary" means (a) sent (b) across a boundary to where the Gospel is not (c) to see a church planted (not just converts made) that (d) can reach everyone in that place without the missionary being present (through the work of witnesses, evangelists, pastors, etc).
A person gifted as a pastor or an evangelist or a missionary should not be persuaded, pressured or demanded to be something they are not.
We need every part of the Body, each to be involved in the work of the Kingdom, doing the thing we are made to do. If indeed we were all missionaries - who would pastor?
