When God opens a door, what possible excuse can we have for not going through it?
All over the world God is opening doors of opportunity today, making it possible for us to take the Gospel to millions who have never heard of Christ. Some live in lands that have been freed in recent years from the grip of atheism; others are immersed in a rising tide of secularism or religious oppression. But in spite of the barriers – and they are real – God is opening doors today in unexpected ways for the preaching of the Gospel. Will we fail to go through them?
What he opens no one can shut, and what he shuts no one can open…. See, I have placed before you an open door that no one can shut.
