The great need for the Christian worker is to be ready to face Jesus Christ at any and every turn. This is not easy, no matter what our experience is. The battle is not against sin or difficulties or circumstances, but against being so absorbed in work that we are not ready to face Jesus Christ at every turn. That is the one great need, not the facing (of) our belief, or our creed; (not) the question (of) whether we are of any use, but to face Him.
Jesus rarely comes where we expect Him; He appears where we least expect Him, and always in the most illogical connections. The only way a worker can keep true to God is by being ready for the Lord's surprise visits. It is not service that matters, but intense spiritual reality,expecting Jesus Christ at every turn. This will give our life the attitude of child-wonder which He wants it to have. If we are going to be ready for Jesus Christ, we have to stop being religious (that is, using religion as a higher kind of culture) and be spiritually real.
...Setting your heart on what He wants, on thinking on His line - you will be called unpractical and dreamy; but when He appears in the burden and the heat of the day, you will be the only one who is ready. Trust no one, not even the finest saint who ever walked this earth, ignore him, if he hinders your sight of Jesus Christ.
