The Bible mentions three main types of enemies: the enemy within, the enemy without and the enemy above. The enemy within is our own inner struggle with sin and temptation. This can manifest in many ways—including jealousy, envy, anger and selfishness. To combat this type of enemy, we must be aware of our imperfections and seek God’s grace and strength to help us overcome them. The enemy without refers to those people who may oppose or hinder our efforts—such as persecutors, adversaries or enemies of the faith. We must respond to these enemies with love and respect, knowing that they too are made in the image of God. Lastly, the enemy above is the devil himself—the accuser of the brethren (Revelation 12:10). We must be aware of his schemes and resist him in the power of the Holy Spirit.
