Do not let the time pass by and you have not come to knowledge of the truth. What truth?
Word of God.
“Seek ye out of the book of the LORD, and read” (Isaiah 34:16) to obtain knowledge of the truth; “Knowing this first, that no prophecy of the Scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost” (2 Peter 1:19–21).
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness” (2 Timothy 3:16).
“They that followeth after righteousness and mercy findeth life, righteousness, and honor” (Proverbs 21:21). “Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life” (1 Timothy 6:19).
