Then again... Do you know Him?  Do you really know Him?  That's easy to tell:  If you've seen God and know him, your life has radically changed, not just a philosophy but a life, True life!  Your way to live tells how good you know Him!  Even for those who know him do not commit sin.

If you don't know Him, how could you get to know Him?  Easy, how do you usually get to know somebody but spending time with that one?  Constantly look for Him, talked to Him, ask Him, not until you feel you said everything that had to be said; but until you get a response, an answer.  With no bi directional communication, no relationship; with no relationship, no way to get to know each other!

I encourage you to be sincere with yourself and become not an evangelical, catholic or any other; but a real son or daughter of God, who knows his/her Father.  And even shows His character on real life.
