You can determine God’s calling by asking three questions. First, what are your desires? What do you long to do? The first qualification of a pastor is that he “desires” the office (1Tm. 3:1). Paul longed to preach (1Cor. 9:16) and Jeremiah said he was like a volcano ready to burst if he stopped preaching (Jer. 20:9). Matthew Henry said that when we make God our heart’s delight, then we’ll have our heart’s desire. When considering a call to the mission field this is one of the many principles that should be considered.
