My flesh and my heart faileth; ButGod is the strength of my heart and my portion for ever.
Flesh and heart must fail, they already have, and will again at death itself, but God will never fail me. He is my strength when all else collapses, my joy forever. Cast your anchor where Asaph cast his: in God alone, for all other things pass away, and only He abides.
AI summary
The psalmist battles carnal reason itself, contending against what the eye sees: the wicked gorged in wealth and pleasure while mocking God, and the righteous crushed under troubles. He nearly cast off all care for religion at this sight. But he reproves his own rashness in judging from the present state alone, and learns that when God's providence runs its course as He has determined in secret counsel, the righteous will not be cheated of their reward, nor the wicked escape the judge.
