Adam Clarke on Psalms 63:2

To see thy power and thy glory - in the sanctuary - In his public ordinances God had often showed his power in the judgments he executed, in the terror he impressed, and in awakening the sinful; and his glory in delivering the tempted, succouring the distressed, and diffusing peace and pardon through the hearts of his followers. God shows his power and glory in his ordinances; therefore public worship should never be neglected. We must see God, says the old Psalter, that he may see us. In his temple he dispenses his choicest blessings.
