2:15 Study. A Christian should be a student, especially a student of the Word of God, but also of the world of God and the works of God. Actually the Greek for “study” (spoudazo) means “be earnest and diligent.”
2:15 dividing. The figure is of a workman or possibly a surgeon, dissecting an object in a very straight line. The word translated “rightly dividing” (Greek orthotomeo) literally means “cutting straight”; it is used only here. That is, the one who would be a faithful teacher of God’s Word must diligently study it and be careful to accept and teach it as it is. This means taking it to mean exactly what the writer intended it to mean, not deviating to right or left. Normally, this would require taking it literally, unless the writer himself makes it evident that he is using symbolic language or a figure of speech. The writers—especially writers inspired by the Holy Spirit—wanted their writings to be understood. Consequently, they would normally use figurative language only if this would make their message easier to understand.
2:15 word of truth. Jesus said: “Thy Word is truth” (John 17:17). “Thy word is true from the beginning,” said the psalmist (Psalm 119:160). The Lord Jesus said “I am the truth” (John 14:6). One who would teach the Bible effectively must teach it as absolute truth, centered in Jesus Christ.
