Known But Not Glorified

Romans 1:21 NIV
For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

A person can know God, even believe that He exists but if he/she does not acknowledge Him from the heart he/she is not a believer. If you truly love something or someone you will not have a problem expressing your love. It is impossible to contain it and do not consider your love a shameful thing. Honor and loyalty give a rightful place. God just doesn’t want to be known or believed that He exists for even the demons and Satan himself acknowledge Him. He wants a heart that is totally devoted to Him: one that is not ashamed, willing to declare before the whole world that He is the one true God. May His name be exalted within us and pour from us to bring light to this darkened world. - JSS
