When we ask God for a thing, such as that He would be pleased to raise up labourers for His harvest, or send means for the carrying on of His work, the honest question to be put to our hearts should be this: Am I willing to go, if He should call me? Am I willing to give according to my ability? For we may be the very persons whom the Lord will call for the work, or whose means He may wish to employ.
