Why are their so many denominations???

Matthew 7:15-23
Beware of false prophets who come to you in sheep's clothing but inwardly are ravaging wolves. You'll recognize them by their fruit. Are grapes gathered from thorn-bushes or figs from thistles? In the same way, every good tree produces good fruit, but a bad tree produces bad fruit. A good tree can't produce bad fruit; niether can a bad tree produce good fruit. Every tree that doesn't produce good fruit is cut down and thrown into the fire. So you'll recognize them by their fruit. "Not everyone who says to Me, 'Lord, Lord!' will enter the kingdom of heaven, but the one who does the will of My Father in heaven. On that day many will say to Me, 'Lord, Lord, didn't we prohesy in Your name, drive out demons in Your name, and do many miracles in Your name?' Then I will announce to them, ' I never knew you! Depart from Me, you lawbreakers!'

Jesus spoke to me in this verse as a weapon agains non-believers. Satan has twisted the christian faith so that the many denominations of christianity are confusing to non-believers. He has shown me that the way to know that the belief system is true and righteous is by the 'fruit' produced by this faith! Thank You Jesus for revealing this to me!!
