Has God decreed death or life for us? Are we blessed or cursed? Are we to love/bless or be harsh/curse others?

But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. Romans 5:8

Bless those who curse you, pray for those who mistreat you. Luke 6:28

Do not gloat when your enemy falls; when he stumbles, do not let your heart rejoice. Proverbs 24:17
