A godly man...
(a) By diligently reading it. The noble Bereans "searched the Scriptures daily" (Acts 17:11). Apollos was mighty in the Scriptures (Acts 18:12). The Word is our Magna Carta for heaven; we should be daily reading over this charter. The Word shows what is truth and what is error. It is the field where the pearl of price is hidden. How we should dig for this pearl! A godly man's heart is the library to hold the Word of God; it dwells richly in him (Col. 3:16). It is reported of Melanchthon that when he was young, he always carried the Bible with him and read it greedily. The Word has a double work: to teach us and to judge us. Those who will not be taught by the Word shall be judged by the Word. Oh, let us make ourselves familiar with the Scripture! What if it should be as in the times of Diocletian, who commanded by proclamation that the Bible be burned? Or as in Queen Mary's days, when it spelled death to have a Bible in English? By diligent conversing with Scripture, we may carry a Bible in our heads.
