Are christians suppose help other christians only?

[DieAmartyr]

I heard a pastor say christians only suppose to help other believer, i think its kind of mess up. What if you see a burning house with a non believers screaming for help do i just sit there or help them? I would try to help them

Untrue. Christians are to help the lost and those who do not know Jesus, and to love all people to an extent

You are not the same as those who do not believe. So do not join yourselves to them. Good and bad do not belong together. Light and darkness cannot share together. 2 Corinthians 6:14

There is a difference between a non- believer and someone who does not know enough about Jesus to choose. A non- believer is someone who has heard about Jesus and rejects Him .
