“I will put my law within them, and I will write it on their hearts; and I will be their God, and they shall be my people” (31:33 NRSV)
“Even Gentiles, who do not have God’s written law, show that they know his law when they instinctively obey it, even without having heard it.” Rom. 2:15
“20For since the creation of the world God’s invisible qualities, His eternal power and divine nature, have been clearly seen, being understood from His workmanship, so that men are without excuse.” Rom. 1:20
“He has also set eternity in the human heart… ” Eccl 3:11
Even the most dyed in the wool atheist knows he is arguing with the facts. His only consolation, his only sense of comfort, is that he can be loud enough to gain a following. But he knows there is a God. He is living and spewing a lie that is a stark affront to everpresent truth, real, good. He knows his life has to robed in good in order to fool a few. He knows there is God the same that the devil and his demons know God is real.
I hope you will give thought to God and what He wants for your life.
