God threatens to damn murderers. But if you do wrong, be afraid, for he does not bear the sword for nothing. He is God's servant, an agent of wrath to bring punishment on the wrongdoer. God gives lawful government the right and responsibility to use deadly force in order to protect human life and punish evil-doers. God protects human life with the Fifth Commandment, threatens murderers with damnation, and charges the government with the protection of human life and the temporal punishment of murderers.
Human life is far more valuable and important than animal life.
Every human is sinful and needs God's mercy. For all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus. Even though all human beings are guilty of sin, God's love is also universal. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.
