With all the desire of his soul - Deuteronomy 18:6
Here is the inspiration of a noble purpose taking a man out from his quiet life in some distant village, far removed from the great sacred city, and plunging him suddenly into the very midst of its holy engagements and services. Other men were happy there. What more did they want than the quiet routine of buying and selling cattle, tending vines, and cultivating their fields? But for this man these could not suffice. There was a light that excelled beckoning him on; a voice, which only he could hear, calling to him. He was not asked to come; his name did not appear on the rota of the Temple servitors; the great Temple might seem perfectly able to dispense with him; yet because with all the desire of his soul he longed to be one of the Temple Levites, he might minister in the name of the Lord, as the others did; and be supported, as they, from the Temple funds.
It is a blessed thing to feel an impulse like this. It may prompt to home or foreign missions, to some enterprise of self-denying ministry to the helpless and sad, to service for God or man. It may come on you like a strong current, fresh from the ocean, sweeping up into some quiet river or harbor basin, and lifting the ponderous barges. But when it comes, be true to it, nurse it, reverence it, thank God for it, trust and follow it where it leads. You will find a niche awaiting you, and the portions by which life will be nourished and maintained; and the Holy Spirit will not fail to be your Guide and Teacher, leading you into all the truth. Until it come, wait upon God in prayer; commune with Him in the Holy of Holies; and spend much time in reading and meditating upon His Holy Word.
