Romans 1:19 Meaning and Commentary

Romans 1:19

Because that which may be known of God
There are some things which could not be known of God by the light of nature; as a trinity of persons in the Godhead; the knowledge of God in Christ as Mediator; the God-man and Mediator Jesus Christ; his incarnation, sufferings, death, and resurrection; the will of God to save sinners by a crucified Jesus; the several peculiar doctrines of the Gospel, particularly the resurrection of the dead, and the manner of worshipping of God with acceptance: but then there are some things which may be known of God, without a revelation. Adam had a perfect knowledge of him; and his sons, though fallen, even the very Heathens have some notion of him, as that there is a God; and by the light of nature it might be known that there is but one God, who is glorious, full of majesty, and possessed of all perfections, as that he is all powerful, wise, good and righteous: and this

is manifest in them,
or "to them"; by the light that is given them: it is light by which that which may be known of God is manifest; and this is the light of nature, which every man has that comes into the world; and this is internal, it is in him, in his mind and conscience, and is communicated to him by God, and that by infusion or inspiration; see ( Job 32:8 ) ;

for God hath showed [it] unto them;
what may be known of him by that light; and which is assisted and may be improved by a consideration of the works of creation and Providence.

Romans 1:19 In-Context

17 For in it the righteousness of God is revealed through faith for faith; as it is written, "The one who is righteous will live by faith."
18 For the wrath of God is revealed from heaven against all ungodliness and wickedness of those who by their wickedness suppress the truth.
19 For what can be known about God is plain to them, because God has shown it to them.
20 Ever since the creation of the world his eternal power and divine nature, invisible though they are, have been understood and seen through the things he has made. So they are without excuse;
21 for though they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their senseless minds were darkened.
