“These are the nations the Lord left to test all those Israelites who had not experienced any of the wars in Canaan (he did this only to teach warfare to the descendants of the Israelites who had not had previous battle experience): The five rulers of the Philistines, all the Canaanites, the Sidonians, and the Hivites living in the Lebanon mountains from Mount Baal Hermon to Lebo Hamath. They were left to test the Israelites to see whether they would obey the Lord’s commands, which he had given their ancestors through Moses.” (Judges 3:1-4, NIV)
In the life of a disciple of Jesus, even one’s enemies are a part of God’s plan.
In today’s scripture reading from the book of Judges, enemies existed to teach the descendents of the Exodus how to defend themselves, and to test their devotion to God. (Please see Judges 2:20-22.)
Today, our biggest threat is not the sword (although physical threats do, indeed, exist); it is, instead, all of the influences and agents that oppose the Spirit of God within us. Even here we must pray for our enemies as we utilize the weapons of the Spirit, which are: Truth, righteousness, the gospel of peace, faith, salvation, and the holy scriptures (word of God).
So, do not curse your enemies. Pray for them. Resist them with the weapons of the Spirit, which are exclusively adequate for spiritual warfare. – Luther
