C.H. Spurgeons's The Treasury of David
Verse 5. O Lord, how great are thy works! He is lost in wonder. He utters an exclamation of amazement. How vast! How stupendous are the doings of Jehovah! Great for number, extent, and glory and design are all the creations of the Infinite One.
And thy thoughts are very deep. The Lord's plans are as marvellous as his acts; his designs are as profound as his doings are vast. Creation is immeasurable, and the wisdom displayed in it unsearchable. Some men think but cannot work, and others are mere drudges working without thought; in the Eternal the conception and the execution go together. Providence is inexhaustible, and the divine decrees which originate it are inscrutable. Redemption is grand beyond conception, and the thoughts of love which planned it are infinite. Man is superficial, God is inscrutable; man is shallow, God is deep. Dive as we may we shall never fathom the mysterious plan, or exhaust the boundless wisdom of the all comprehending mind of the Lord. We stand by the fathomless sea of divine wisdom, and exclaim with holy awe, "O the depth!"
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 5. Thy thoughts. The plural of tbfrm, from the verb bfr, to meditate, to count, to weave; and this last word gives a good idea of what is here made the subject of admiration and praise, the wonderful intricacy and contrivance with which the Divine Mind designs and executes his plans, till at length the result is seen in a beautifully woven tissue of many delicately mingled and coloured threads. --Christopher Wordsworth.
Verse 5. Thy thoughts are very deep. Verily, my brethren, there is no sea so deep as these thoughts of God, who maketh the wicked flourish, and the good suffer: nothing so profound, nothing so deep; therein every unbelieving soul is wrecked, in that depth, in that profundity. Dost thou wish to cross this depth? Remove not from the wood of Christ's cross; and thou shalt not sink: hold thyself fast to Christ. --Augustine.
HINTS FOR PASTORS AND LAYPERSONS
Verse 5. The unscalable mountains and the fathomless sea: or the divine works and the divine thoughts (God revealed and hidden) equally beyond human apprehension. -- C.A. Davis.
