Psalms 145:3

His greatness is unsearchable.

The unsearchableness of God

God transcends all thoughts; notwithstanding this, men should search after His greatness.

I. Searching after His greatness is a righteous occupation.

1. It agrees with the profoundest instincts of the soul.

2. It is stimulated by the manifestations of nature.

3. It is encouraged by the declarations of the Bible.

4. It is aided by the revelations of Christ.

II. Searching after His greatness is a useful occupation.

1. There is no occupation so quickening to the soul. Feeling after God is an inspiration.

2. There is no occupation so humbling to the soul. The idea of the Infinite drives all vanities from the soul, and brings it down from the heights of pride into the deepest valley of humiliation.

3. There is no occupation so ennobling to the soul. The idea which brings us down into the valley of humiliation stimulates us to climb the heights of moral greatness.

III. Searching after His greatness is an endless Occupation. “Canst thou, by searching, find out God?”

1. All holy intelligences have ever been pursuing this work.

2. The endlessness of this pursuit agrees with--

(1)The inexhaustible powers of our nature.

(2) The strong instinct for mystery within us. (D. Thomas, D. D.)
