Psalm 78 is the second longest psalm in the Hebrew songbook. Its summation of Israel’s history as a nation clearly demonstrates the immense need for vigilance and steadfastness in the faith.
Israel’s checkered history is one of divine deliverance being repaid by human sin and rebellion (vv. 12-19); Jehovah’s provisions being despised through unbelief and more sin (vv. 20-32); apostasy following closely on the heels of repentance (vv. 33-37); and, spiritual amnesia being the chosen response to God’s compassion and mercy (vv. 38-58).
How challenging it is for God’s people to maintain the vigilance they need for spiritual victory! How easy it is to fall from the steadfastness that spiritual victory requires!
How immensely needed are the words of 1 Peter 5:8-9—”Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. Resist him, steadfast in the faith.”
