Don’t confuse platform, proclamation and planting.
Everyone has a platform, by which they interact with the people around them.
Everyone is responsible to proclaim: to be a witness for what they have seen, to announce good news, to make disciples.
Everyone can be involved in some kind of planting: to help create the processes by which the Gospel is sustained over time.
These are three separate things, which are inextricably linked but are not identical.
