1. Our struggle is a spiritual one (10-12)

Our enemies are not people. The devil is our enemy, and our real battle is a spiritual one. We cannot defeat such an enemy by our human strength, so we must be strong in the Lord and in his mighty power.

2. Put on the armor of God (13-24)

We can be strong when we put on the whole armor of God. The belt of truth helps us keep our balance. The breastplate of righteousness protects out hearts from temptation. With the gospel of peace on our feet, we are ready to go anywhere to preach the gospel. The gospel gives peace with God and peace among men. The shield of faith guards our hearts from the arrows of doubt and fear. The helmet that protects our heads is our assurance of salvation; we wear it with a shout of victory. The sword of the Spirit, the Bible, is our one weapon. The Holy Spirit works through his word. It is essential that we be alert and prayerful.

Application: Lord, clothe me in your armor so that I may fight the devil today.
One Word: Be strong in the Lord
