'Duck Dynasty' Star Uncle Si Talks About Faith in Christianity in Upcoming Book "Si-Cology 1: Wisdom from Duck Dynasty's Favorite Uncle" / New Episode [TRAILER] 

Silas Robertson, or as Duck Dynasty fans know him, Uncle Si, may have earned a reputation for being the outlandish, borderline delusional Robertson family member, but his faith in God and Christianity has kept him grounded through a 43 year marriage, and a 25 year stint in the military. He talks about his faith in his upcoming book "Si-Cology 1: Tales and Wisdom From Duck Dynasty's Favorite Uncle".

Though his family members often times tease his abnormal antics, he believes no man on Earth has the right to condemn any other. If Jesus didn't condemn another then no one has that power.

"When I sign people's stuff, I put down John 3:16 and 17. Most people can tell you what 16 says, 'For God so loved the world that He gave His only begotten son.' But they don't know nothing about 17,'" Si told The Christian Post. "It says Jesus didn't come to condemn us. If anybody had a right to condemn someone, it would be the son of God. If he didn't do it, then hey, we definitely are not qualified to do it."

Black sheep of the Robertson clan, and oldest son of Phil and Miss Kay, Alan Robertson, who is now a pastor, doesn't condemn aethists and agnostics but does confess he's confused by their thought process.

"A person asked me one time, what's the evidence that God is there? And I said, 'I'll go out here and pick up an acorn from under a tree. You put it in the ground and water it and 40 years later when you come back, there might be an oak tree as big around as a pick-up truck.' Inside that little acorn is the resurrection power," Alan told the Christian Post. "That has to come from somewhere. It didn't just exist."

Tune in for Duck Dynasty Season 4 Wednesday nights at 10/9c on AMC.
