How do I know that god exist? There's no evidence that he does.
It's up to you to find out. It isn't hard so I'll give a scripture that makes your belief your choice. 2 scriptures in fact.
Revelation 3:20-21 (KJV)
[SUP]
20 [/SUP]Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
[SUP]
21 [/SUP]To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
John 3:11-12 (KJV)
[SUP]
11 [/SUP]Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
[SUP]
12 [/SUP]If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you
of heavenly things?
