'Accursed' in the Bible

We work [for our living], working hard with our own hands. When we are reviled and verbally abused, we bless. When we are persecuted, we take it patiently and endure.

Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost.

If anyone does not love the Lord, he is to be accursed. Maranatha.
