What does Jude 1:4-10 reveal about who God the Father is?
God is gracious. He does not treat sinners as they deserve but he adopts them into his family (Jude 1:1).
God is judge. The Israelites in the wilderness were destroyed, the angels are kept for judgment. God will act to punish sin.
4 For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ.
