The concept of ‘doors’, is helpful to the disciple for making decisions:
In some places, or amongst some groups, you’ll have an open door to share about Jesus, and do good work.
In other places, amongst other groups, at certain times, you won’t. The door’s just kinda shut.
An open door doesn’t mean lack of opposition, it just means plenty of opportunity. (1 Corinthians 16:9)
You don’t have to walk through an open door. (2 Corinthians 2:12-13)
But after knocking a couple of times, you should walk away from a closed one. Part of Jesus’ training is how to shake the dust off your feet. Don’t waste your spiritual warfare, “violent-men-taking-hold-of” mode on closed doors. That blunt instrument, Paul, didn’t.
Sometimes previously open doors shut, other times closed doors open. But know this – there are open doors out there for you.
So pray. For you and your people, pray for doors flinging wide today. (Colossians 4:2-4)
And when one does, if it’s right, walk right through.
