Study and Meditate the Word of God
2Ti 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
Study the Bible, dear brethren, through and through, with all helps that you can possible obtain. Remember that the appliances now within the reach of ordinary Christians are such more extensive than they were in our father's days, therefore you must be greater Biblical scholars if you keep in front of your hearers. Intermeddle with all knowledge. But above all things, meditate day and night in the law of the Lord.
