Charles H. Spurgeon on Psalms 90:12

1. The Reckoning. (a) What their usual number. (b) How many of them are already spent. (c) How uncertain the number that remains. (d) How much of them must be occupied with the necessary duties of this life. (e) What afflictions and helplessness may attend them.

2. The use to be made of it. (a) To "seek wisdom" —not riches, worldly honours, or pleasures —but wisdom; not the wisdom of the world, but of God. (b) To "apply the heart" to it. Not mental merely, but moral wisdom; not speculative merely, but experimental; not theoretical merely, but practical. (c) To seek it at once —immediately. (d) To seek it constantly —"apply our hearts", etc.

3. The help to be sought in it. "So teach us", etc. (a) Our own ability is insufficient through the perversion both of the mind and heart by sin. (b) Divine help may be obtained. "If any man lack wisdom." etc. —G.R.
