It is easy to imagine that we will get to a place where we are complete and ready, but preparation is not suddenly accomplished, it is a process steadily maintained. It is dangerous to get into a settled state of experience. It is preparation and preparation.
The sense of sacrifice appeals readily to a young Christian. Humanly speaking, the one thing that attracts to Jesus Christ is our sense of the heroic, and the scrutiny of Our Lord’s words suddenly brings this tide of enthusiasm to the test. "First be reconciled to thy brother." The "go" of preparation is to let the word of God scrutinize. The sense of heroic sacrifice is not good enough. The thing the Holy Spirit is detecting in you is the disposition that will never work in His service. No one but God can detect that disposition in you. Have you anything to hide from God? If you have, then let God search you with His light. If there is sin, confess it, not admit it. Are you willing to obey your Lord and Master whatever the humiliation to your right to yourself may be?
Never discard a conviction. If it is important enough for the Spirit of God to have brought it to your mind, it is that thing He is detecting. You were looking for a great thing to give up. God is telling you of some tiny thing; but at the back of it there lies the central citadel of obstinacy: I will not give up my right to myself – the thing God intends you to give up if ever you are going to be a disciple of Jesus Christ.
