The God of the bible does not tell you to murder unbelievers.
Sure it does:
Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must be put to death. Such evil must be purged from Israel. (Deuteronomy 17:12 NLT)
You should not let a sorceress live. (Exodus 22:17 NAB)
"If a man lies with a male as with a women, both of them shall be put to death for their abominable deed; they have forfeited their lives." (Leviticus 20:13 NAB)
A man or a woman who acts as a medium or fortuneteller shall be put to death by stoning; they have no one but themselves to blame for their death. (Leviticus 20:27 NAB)
If a man commits adultery with another man's wife, both the man and the woman must be put to death. (Leviticus 20:10 NLT)
A priest's daughter who loses her honor by committing fornication and thereby dishonors her father also, shall be burned to death. (Leviticus 21:9 NAB)
Whoever sacrifices to any god, except the Lord alone, shall be doomed. (Exodus 22:19 NAB)
They entered into a covenant to seek the Lord, the God of their fathers, with all their heart and soul; and everyone who would not seek the Lord, the God of Israel, was to be put to death, whether small or great, whether man or woman. (2 Chronicles 15:12-13 NAB)
Suppose you hear in one of the towns the LORD your God is giving you that some worthless rabble among you have led their fellow citizens astray by encouraging them to worship foreign gods. In such cases, you must examine the facts carefully. If you find it is true and can prove that such a detestable act has occurred among you, you must attack that town and completely destroy all its inhabitants, as well as all the livestock. (Deuteronomy 13:13-19 NLT)
If your own full brother, or your son or daughter, or your beloved wife, or you intimate friend, entices you secretly to serve other gods, whom you and your fathers have not known, gods of any other nations, near at hand or far away, from one end of the earth to the other: do not yield to him or listen to him, nor look with pity upon him, to spare or shield him, but kill him. (Deuteronomy 13:7-12 NAB)
Make ready to slaughter his sons for the guilt of their fathers; Lest they rise and posses the earth, and fill the breadth of the world with tyrants. (Isaiah 14:21 NAB)
and finally this verse gives reason for the crusades.
Cursed be he who does the Lords work remissly, cursed he who holds back his sword from blood. (Jeremiah 48:10 NAB)
You can't be picking and choosing, Bill, if you want credibility.
