Matthew, Chapter 10:verse 28
And do not be afraid of those who kill the body but cannot kill the soul; rather, be afraid of the one who can destroy both soul and body in Gehenna.
Matthew, Chapter 25: verse 41
Then he will say to those on his left, 'Depart from me, you accursed, into the eternal fire prepared for the devil and his angels.
Matthew, Chapter 13:verses 24-30
He proposed another parable to them. “The kingdom of heaven may be likened to a man who sowed good seed in his field. While everyone was asleep his enemy came and sowed weeds all through the wheat, and then went off. When the crop grew and bore fruit, the weeds appeared as well. The slaves of the householder came to him and said, ‘Master, did you not sow good seed in your field? Where have the weeds come from?’ He answered, ‘An enemy has done this.’ His slaves said to him, ‘Do you want us to go and pull them up?’ He replied, ‘No, if you pull up the weeds you might uproot the wheat along with them. Let them grow together until harvest; then at harvest time I will say to the harvesters, “First collect the weeds and tie them in bundles for burning; but gather the wheat into my barn.”’”
-The Word of the Lord
If God proposes damnation then it is not out of the question that he can also kill a man.
