The fierce, sometimes unbearable spiritual conflict that assails the believer — encompassing doubt, despair, accusation, the sense of God's absence or wrath, and the temptation to abandon faith altogether. Anfechtung is not mere sadness or discouragement; it is the experience of being under siege from within and without, where Satan, the flesh, and even the apparent silence of God conspire to crush the soul.
Yet Scripture reveals that Anfechtung serves a redemptive purpose: God permits the furnace of trial to purify faith (1 Pet. 1:6–7), to drive the believer deeper into dependence on grace, and to produce a tested, unshakable trust. The Psalms of lament (Ps. 22, 42, 88) are the songbook of Anfechtung — raw cries from souls who feel God-forsaken yet refuse to release their grip on the God who seems to have released His grip on them.
Not included in Webster 1828 as an English entry. The concept corresponds to what the Puritans called "spiritual desertion" or "the dark night of the soul" — seasons in which the sensible presence of God withdraws, the believer feels abandoned, and faith is reduced to sheer, naked trust in a God who seems unreachable. Luther distinguished Anfechtung from ordinary temptation: it is not merely the lure to sin, but the assault upon the very foundations of one's faith and identity in Christ.
Modern therapeutic Christianity has no category for Anfechtung. Spiritual darkness is medicalized, explained away, or treated as evidence of insufficient faith. The prosperity gospel promises perpetual spiritual sunshine; the self-help gospel offers coping strategies. Both fail the believer in the furnace. Meanwhile, secular culture reduces all inner torment to clinical pathology — stripping spiritual warfare of its spiritual dimension entirely. The truth is more dangerous and more comforting: God is closest in the darkness (Ps. 139:12), and the faith that emerges from Anfechtung is unbreakable precisely because it survived without props.
Psalm 22:1–2 — "My God, my God, why have You forsaken me? Why are You so far from saving me, from the words of my groaning?"
1 Peter 1:6–7 — "In this you rejoice, though now for a little while you have been grieved by various trials, so that the tested genuineness of your faith… may be found to result in praise."
Psalm 88:1–6 — "O LORD, God of my salvation… my soul is full of troubles, and my life draws near to Sheol."
2 Corinthians 1:8–9 — "We were so utterly burdened beyond our strength that we despaired of life itself… but that was to make us rely not on ourselves but on God."
Job 23:8–10 — "Behold, I go forward, but He is not there… But He knows the way that I take; when He has tried me, I shall come out as gold."
Anfechtung is the crucible in which nominal faith either disintegrates or becomes unshakable conviction. It is God's severe mercy — permitting the storm so the roots go deeper.
Luther considered his own Anfechtungen among his greatest theological teachers: "I did not learn my theology all at once. I had to ponder over it ever deeper, and my Anfechtungen were of help to me in this."
The Christian who has never experienced Anfechtung may have never been tested. The Christian who has survived it knows something about God that comfort cannot teach.
