Every shepherd has at least two tools—a rod and a staff—that help him skillfully lead and care for his sheep. The shepherd’s rod was a firm wooden stick, fashioned like a club, and used to guard defenseless sheep from the attack of wild animals.
For David, the shepherd and psalmist, the rod was a symbol of divine power, authority, and defense. The connection between the rod of God and the word of God is significant.
The Bible—all sixty-six books and every word contained therein—speaks with divine authority. We could write across the Bible’s cover, “Thus saith the Lord.” Truly, the Bible is the rod of God, an indispensable tool in the hands of pastoral shepherds who lead the church of Jesus Christ.
