Definition of Theology 
The word theology is derived from two Greek words: theos, God; and logos, discourse. Theology Proper is the study of the knowledge of God and His relation to mankind. The student of God’s Word, the Bible, has the privilege of constructing and presenting a comprehensive and consistent system of thought concerning the God of the universe who has revealed Himself in various ways to His creation. The quest to know the Lord (Jer. 29:13) must be made according to truth with faith in the promise of Jesus who said, “Ye shall know the truth and the truth shall set you free” (John 8:32). 
Theology is Universal 
Every thoughtful individual is a theologian to some extent for life and destiny are affected by what an individual believes about God and His will. According to Proverbs 23:7, "As a man thinketh in his heart so is he.” "Nothing so affects the spirit and character of a person as his knowledge of God, or the lack of it." (David Clark) Because this is true, theology becomes the most vital and fundamental of all studies. “To this consideration, individuals may well bring the liveliest interest, keenest apprehension, and loftiest powers of the mind. People may engage in the most diligent of spiritual labors while calling upon the soul and all that is within the soul to attend seriously and reverently to the great and solemn subjects that concern God.” (David Clark) The spiritual heart prays with the Psalmist (119:18), "Lord, open thou mine eyes that I may behold wondrous things out of thy law”. Such a prayer is needed because, "Nothing twists and deforms the soul more than a low or unworthy conception of God." (A.W. Tozer)
