Without opposition and adversity we cannot grow as Christians or be transformed. This is a truth of the cross. We need our enemies. They facilitate our death to self and the resurrection which follows. Actually, properly viewed, our enemies really become our friends because we realize that by opposing us, humiliating us and putting us down, they take us where we need to go--down into humility; down down deeper into the death and burial of Christ. Consequently, we are then raised up higher and higher. The deeper the higher. This is why we can come to the point of truly loving our enemies. Matt 5:38-48. Enemies are springboards for Christian growth.
Are you thankful for your enemies? You would never mature as a Christian if you were constantly only surrounded by friends and well-wishers.
Scriptures prove this truth of the cross:
In Acts 27, it was the hurricane winds that took Paul and Rome's captives on board ship where they needed to go. And as the enemy shipmen were about to flee out of the ship, Paul said to the Centurion and the soldiers, "Except these (enemy shipmen) abide in the ship ye cannot be saved." They needed opposition in order to be saved from the storm.
In Matt 13:36-43, Jesus warned that the poisonous tares should not be uprooted because their uprooting would jeopardize the growth of the good wheat. The wheat needed the opposition of the tares in the midst of the field (the church) in order to remain healthy and vibrant.
