God’s witness and revelation of himself has been evident in his providence and creation. He has established seasons that provide a measure of order in this world instead of chaos. He also caused the sun to shine on all people (Matthew 5:45). This order should have prompted the people to worship the Creator only, but they failed to do so because of their sinful nature (see Romans 1:19–23). Paul argues that human beings should have reasoned from effect (order in creation) to cause (God who is Creator) (see Jeremiah 5:23–24).1
17 quoiqu'il n'ait cessé de rendre témoignage de ce qu'il est, en faisant du bien, en vous dispensant du ciel les pluies et les saisons fertiles, en vous donnant la nourriture avec abondance et en remplissant vos cœurs de joie.
