Suffering can feel like an endless night. Psalm 23 pictures the Lord as the shepherd who rules the valley, stays with His sheep, and carries a rod and staff to protect and correct them. Jesus entered the deepest darkness at the cross, forsaken under judgement, so those who trust Him will never be abandoned there. He guards them from eternal harm, draws them back from sin, and leads them into God's presence, where every tear will be wiped away.
