until I entered God’s sanctuary; then I discerned their end.
When the psalmist stepped into God's sanctuary, he shifted his entire point of view. From earth's vantage, the wicked's prosperity appears victorious; from the sun's fixed observatory, all planets move in perfect order. He saw their end with enlightened eyes and his envy turned to holy horror at their impending doom. No longer did he covet their condition.

Until I went into the sanctuary of God; [then] understood I their end. (h) Until I entered into your school and learned by your word and Holy Spirit that you order all things most wisely and justly.
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.
