Then the word of God spread, and the number of the disciples multiplied greatly in Jerusalem, and a great many of the priests were obedient to the faith. – Acts 6:7

If we pant to see the Word of God increase, multitudes added to the disciples, and a great company of those who are least likely to be saved brought in, there must be an adequate instrumentality. Nothing can avail without the operation of the Holy Spirit and the smile from heaven. Paul planteth, Apollos watereth, and God giveth the increase. We must never begin our catalogue of outward means without referring to that blessed and mysterious Potentate who abides in the church, and without whom nothing is good, nothing efficient, nothing successful.

“Come, Holy Spirit, heavenly dove,
With all Thy quickening powers.”

This should be our first prayer whenever we attempt to serve God, for if not, we begin with pride, and can little hope to succeed by prowess. If we go to the warfare at our own charges we must not marvel if we return stained with defeat. O Spirit of the living God, if it were not for Thy power we could not make the attempt, but when we rely upon Thee, we go forward in confidence. ~ C.H. Spurgeon
