Love what Oswald Chambers says on this subject. Think it is among the best descriptions I have ever heard on the call of God, and it certainly suggests the total abandonment that authenticates the call. I especially love his reference to “the glow.” Be blessed in reading this excerpt, from The Complete Works volume. Let’s keep it in front of us and close to heart.
We are apt to forget the mystic supernatural touch of God which comes with his call. If a man can tell you how he got the call of God and all about it, it is questionable whether he ever had the call. A call to be a professional man may come in that explicit way, but the call of God is much more supernatural. The realisation of the call of God in a man’s life may come with a sudden thunder clap or by a gradual dawning, but in whatever way it comes, it comes with the under-current of the supernatural, almost the uncanny. It is always accompanied with a glow – something that cannot be put into words. We need to keep the atmosphere of our mind prepared by the Holy Spirit lest we forget the surprise of the touch of God on our lives. – Oswald Chambers
