Before engaging in battle, a wise warrior dons appropriate armor, including the breastplate that shields vital organs. But battle armor is only for those who have enlisted in the cause. Alistair Begg urges us to consider whether we are soldiers of the cross, entrusting ourselves entirely to Christ on the basis of His finished work. The righteousness that guards our hearts is not earned through our performance, but imputed to us by grace through faith in Jesus. When buffeted by Satan’s arrows of doubt, fear, and disappointment, we can resist by continuing to trust the Gospel, confident that our standing before God has been secured. Bible passages: Ephesians 6:14
