It also involves listening to people, for how shall we know what part of God's Word we should speak to them unless we know where they are at. What I am saying is, you must be willing to study and you must be willing to get close to people. Our churches require their prospective ministers to do a course of training which includes subjects like the Bible, exegesis, theology, philosophy, Greek and Hebrew. So, you've got to be able to think. And you've got to be able to pass on what you have learned.
Some people are great thinkers but hopeless talkers.
And yes, there are great talkers who are hopeless thinkers. The ministry requires men who are able to do a bit of both. Love, a love for the Lord and a great love for His people and for the lost. Love means being willing to do something for another. It means a willingness to deny yourself.
