Greetings Bailey, and welcome to Christian Forums.
This is actually a hard one. I know Paul talked about the mind of the flesh being constantly at war with the mind of the Spirit, or as one translation put it, "7 The sinful mind is at war with God. It does not obey God's law. It can't. 8 Those who are controlled by their sinful nature can't please God."
But as far as the wicked being constant enemies of God, I'm not sure what verse you are looking for.
Here is a list of verses on the subject of God's enemies. Maybe you can find it there, and God bless:
