This unction is not an inalienable gift. It is a conditional gift, and its presence is perpetuated and increased by the same process by which it was at first secured; by unceasing prayer to God, by impassioned desires after God, by estimating it, by seeking it with tireless ardor, by deeming all else loss and failure without it. How and whence comes this unction? Direct from God in answer to prayer. Praying hearts only are the hearts filled with this holy oil; praying lips only are anointed with this divine unction. Prayer, much prayer, is the price of preaching unction; prayer, much prayer, is the one, sole condition of keeping this unction. Without unceasing prayer the unction never comes to the preacher. Without perseverance in prayer, the unction, like the manna overkept, breeds worms. XVII. _Give me one hundred preachers who fear nothing but sin and desire nothing but God, and I care not a straw whether they be clergymen or laymen; such alone will shake the gates of hell and set up the kingdom of heaven on earth. God does nothing but in answer to prayer._--JOHN WESLEY. The apostles knew the necessity and worth of prayer to their ministry. They knew that their high commission as apostles, instead of relieving them from the necessity of prayer, committed them to it by a more urgent need; so that they were exceedingly jealous else some other important work should exhaust their time and prevent their praying as they ought; so they appointed laymen to look after the delicate and engrossing duties of ministering to the poor, that they (the apostles) might, unhindered, “give themselves continually to prayer and to the ministry of the word.” Prayer is put first, and their relation to prayer is put most strongly--“give themselves to it,” making a business of it, surrendering themselves to praying, putting fervor, urgency, perseverance, and time in it.
