We know Him by two means: First, by the creation, preservation, and government of the universe; which is before our eyes as a most beautiful book,1 wherein all creatures, great and small, are as so many letters leading us to perceive clearly the invisible things of God, namely, His eternal power and deity, as the apostle Paul says (Rom 1:20). All these things are sufficient to convict men and leave them without excuse. Second, He makes Himself more clearly and fully known to us by His holy and divine Word2 as far as is necessary for us in this life, to His glory and our salvation.

1Ps 19:1-4 The heavens declare the glory of God; And the firmament showeth his handiwork. 2 Day unto day uttereth speech, And night unto night showeth knowledge. 3 There is no speech nor language; Their voice is not heard. 4 Their line is gone out through all the earth, And their words to the end of the world. In them hath he set a tabernacle for the sun,

2Ps 19:7-8 The law of Jehovah is perfect, restoring the soul: The testimony of Jehovah is sure, making wise the simple. 8 The precepts of Jehovah are right, rejoicing the heart: The commandment of Jehovah is pure, enlightening the eyes.

1 Cor 1:18-21 For the word of the cross is to them that perish foolishness; but unto us who are saved it is the power of God. 19 For it is written, I will destroy the wisdom of the wise, And the discernment of the discerning will I bring to nought. 20 Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of the world? 21 For seeing that in the wisdom of God the world through its wisdom knew not God, it was God's good pleasure through the foolishness of the preaching to save them that believe.
