When the Gentiles, which have not the law, do by nature the things contained in the law, these having not the law are a law unto themselves. Romans 2:14
"God has by various agencies placed enough light in the heart of every 
man to lead him to know the true God.
---Even nature itself reveals the God of nature.
And if a man in the darkest heathenism has a desire to know the true God, he will, if necessary, send a man around the world to give him the light of truth.
Every man that is finally lost will have rejected light that, if cherished, would have led him to God."
Every man that is finally lost will have rejected light that, if cherished, would have led him to God."
E.J. Waggoner
