Much of what is spoken of God, by those trying to bring others into the sheepfold of Christ, is his love. Little is made known about his wrath, though the Bible speaks of it more than it does of his love. He has made himself known to everyone through his creation. You cannot look at the intricate details of the creatures of this earth and not see God’s hand. He deserves the utmost respect and genuine love. When he doesn’t get that love, and we reject him, he pours out his wrath. He loves his children, and because we love Jesus, he will take vengeance on our adversaries. Those who continually deny him, spit in his face, and shake their fists at him, can expect his wrath. I’m not trying to make you afraid, you are not subject to his wrath, but you should have a healthy fear of what God can do, he is not to be toyed with. Honor, love, and respect him. If you need to encourage someone in this, take a look at some of the stories in the Old Testament. Those who rejected him were punished. Remember, one of God’s attributes is that he doesn’t change; he was wrathful then, and he is wrathful now.
“Rejoice with him, O heavens; bow down to him, all gods, for he avenges the blood of his children and takes vengeance on his adversaries. He repays those who hate him and cleanses his people's land.” Deuteronomy 32:43
