"But if the discontent with your present situation is deep, recurrent, and lasting, and if that discontent grows in Bible-saturated soil, God may be calling you to a new work. If, in your discontent, you long to be holy, to walk pleasing to the Lord, and to magnify Christ with your one, brief life, then God may indeed be loosening your roots in order to transplant you to a place and a ministry where the deep spiritual ambitions of your soul can be satisfied. It is true that God can be known and enjoyed in every vocation; but when he deploys you from one place to the next, he offers fresh and deeper drinking at the fountain of his fellowship. God seldom calls us to an easier life, but always calls us to know more of him and drink more deeply of his sustaining grace. "
