Mark 7:7 and Matthew 15:9
"They worship me in vain; their teachings are merely human rules"
"Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles? Then I will tell them plainly, 'I never knew you. Away from me, you evildoers!"
This is what Jesus will say to most Christians who took Jesus as God and started worshipping him as God. Jesus was a mighty prophet and messiah. One of the main reason for his second coming is to break the cross and tell most all Christians that they were wrong in worshiping him.
