A person’s words should reflect his character. A man who is true should speak the truth. God is the God of truth and the God of truth cannot lie. The Bible is true because it is His Word. It is the Word of Truth. Moreover, it is the Word of Power, and the Word of Holiness (Holy Bible), because it reflects the character of the author.
And you learn theology by studying the Bible. Reading its pages will bring to your heart and mind concepts and thoughts of God that are true to Him. God is love, God is light, God is life. Reading the Bible will give you an accurate and true understanding of the one and only true God. And you will think of Him as He is – in His greatness, in His goodness, in His glory.
A much more familiar term is ‘Scripture’. Scripture is the written word of God. It is the Word of God in a more permanent and convenient form. The written word can be studied, examined, quoted. God’s Word has been written down – it is firm, it is sure. It has been written on many materials—papyri, clay, cloth, stone, paper. The Old Testament tells of a time when it was written on a rock. The New Testament tells us it can be written on the heart.
