Why is the friendship of the world considered enmity with God?

In James 4:4, it is stated that friendship with the world equates to enmity against God, emphasizing that believers cannot align themselves with worldly principles and still claim to love God fully. True allegiance to God requires a rejection of worldly influences that promote self-interest and pride. By acknowledging Christ's sovereignty and embracing the values of His kingdom, believers should therefore seek first His righteousness rather than be entangled in the affairs of this world. The seriousness of this enmity underscores the call to holy living distinctly separate from the secular culture.
