The steps of a man are established by the LORD, when he delights in his way; though he fall, he shall not be cast headlong, for the LORD upholds his hand. Psalm 37:23-24
Ps 37:14 uses the same word translated “fall” here. There it is translated “bring down” and the cause is an enemy aiming his deadly arrows at the Psalmist (Eph 6:16). It appears this “fall” is an evil interruption into the life of a devoted follower of the Lord. Sometimes devout believers can fall badly. The great king David is a prime example of this. Yet the delight of God is seen in this—they get up again and continue following, even if with a limp. Falls are not the end of the story. Never the end when God is involved!
“The righteous falls seven times and rises again, but the wicked stumble in times of calamity.” Prov 24:16
