I found an old book by John Gerstner in my library. The first chapter was the author’s appeal for everyone to be a theologian. The book is titled Theology for Everyman. So far, after two chapters, I feel it is a wonderful read.
The appeal from Dr. Gerstner in the first chapter sets the stage for the entire book. To know about God is to be a theologian. Not a full-time professional theologian like that of Dr. Gerstner, now deceased; but to be a good lay theologian. You need not go to seminary to gain a post secondary degree to be a theologian, but you do need a Bible and a humble heart ready to learn. Theology is not for pastors or Bible scholars only. It is for all men and women. All can be a theologian.
Dr. Gerstner lays the groundwork for the argument by stating the lack of knowledge of God is basically a sin along with reality of such it is detrimental to your soul. He makes sure we do not confuse simply having a knowledge of God as being salvific because one can have a knowledge of God and still be lost in sin. The idea rather is: to be a Christian is to have a true knowledge of God.
Faith comes by hearing and hearing the word of God (Rom. 10:17). There is something to be known about God, Jesus, ourselves, and God’s redemptive grace before we can believe it. One must know about God to believe the gospel of God. Likewise, one can know all these things and still be lost. The devils know God and tremble (James 2:19). Yet, reserved for these demons is only destruction (Jude 6). But for the Christian, you know something and this informs your decision to follow Christ in your life.
This knowledge trickles down to an informed life throughout. Since we know God and know things about God, we know how he would have us live. I enjoyed how Dr. Gerstner made this appeal to the reader. This is something that is to be pursued joyfully as it brings much joy. I believe it was RC Sproul, who was mentored by Dr. Gerstner, who furthered this thought by saying everyone is a (already) theologian, the question is weather you are a good one or not? That is to say, all have a knowledge of God (as we see in Romans 1) but do use it as we ought? Be a theologian, a good one. SDG.
