IF Christ is your sufficiency there can be no lack there. Consider the matter carefully. You are going, you may say, to visit some sick person. Who is going? I want to know. Is it some nice Christian? Some kind lady or gentleman? That won’t do! It should be CHRIST. But just think of the gravity of Christ’s doing it. If you are going for Him, you must be in unison with Him about it. The very fact of the importance of the work, and the danger of misrepresenting Him shows your need ―and brings you to realize His faithful word, “Without Me ye can do nothing.”
The neglect of this is the secret of all failure. I will sit lowest here, if you like; but I repeat it; this is the cause of all failure.
