To your two "c" revelations I add two more...they are my "four c's"...creation, conscience, circumstances (Acts 17:26-27, and the desire for ceaseless existence (immortality, Ecc. 3:11)It relates to both in that both have received revelation from God which is "clearly seen" and "understood" thus making them without excuse. They are held accountable to the level of that revelation. As I've quoted before:
God has revealed Himself in creation ( Romans 1:18-20 ) and in human conscience ( Romans 2:12-16 ). Paul said that each individual will be judged according to his response to these two revelations of God. To those who respond positively, God gives more knowledge—as He did to the Ethiopian eunuch and the Roman centurion, Cornelius (see Acts 8,10 ). Those who are lost will be judged according to their response to the spiritual light they have received ( Hebrews 4:12-13 )
That servant who knows his master’s will and does not get ready or does not do what his master wants will be beaten with many blows. But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked ( Luke 12:47-48 ).
This is clearly God reaching out to man first, providing him with everything needed to truly seek Him, and condemning those who reject His grace.
