Are athiests without excuse? http://www.wels.net/sab/frm-bel.html "God has revealed himself in nature. "The heavens declare the glory of God; the skies proclaim the work of his hands" (Psalm 19:1). "Since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that men are without excuse" (Romans 1:20). So there is no excuse for atheists. Since the requirements of the law are written on people's hearts, the consciences of people also bear witness that there is a God to whom they are accountable (Romans 2:15). However, nature and conscience present only a partial revelation of God and one that is not able to show the way to heaven." Yes. What is even worst, is having God, believing God... The Holy Spirit dwelling in you, and denying him. That is blasphemy of the Holy Spirit and is the unforgivable sin. Matthew 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
