If the Spirit of God is at work in your life, nothing will stop you from making this commitment. You have nothing to fear in telling someone that. You have nothing to fear in saying to someone, “I want you to think about this, I want you to consider the cost carefully.” You have nothing to fear. What you're doing is stopping people from superficial, non-saving delusion. You're backing them off and saying, let's find out whether this is really the work of the Spirit of God and what is happening in your life is not a momentary, emotional thing, but what is happening in your life is the true, regenerating work of the Holy Spirit producing an unrelenting repentance and an undying faith that will go through every barrier. You do all the important things in life by calculating carefully. This is the most important thing you'll ever do.
John MacArthur
