10 Last of all I want to remind you that your strength must come from the Lord’s mighty power within you. 11 Put on all of God’s armor so that you will be able to stand safe against all strategies and tricks of Satan. 12 For we are not fighting against people made of flesh and blood, but against persons without bodies—the evil rulers of the unseen world, those mighty satanic beings and great evil princes of darkness who rule this world; and against huge numbers of wicked spirits in the spirit world.
13 So use every piece of God’s armor to resist the enemy whenever he attacks, and when it is all over, you will still be standing up.
14 But to do this, you will need the strong belt of truth and the breastplate of God’s approval. 15 Wear shoes that are able to speed you on as you preach the Good News of peace with God. 16 In every battle you will need faith as your shield to stop the fiery arrows aimed at you by Satan. 17 And you will need the helmet of salvation and the sword of the Spirit—which is the Word of God.
18 Pray all the time. Ask God for anything in line with the Holy Spirit’s wishes. Plead with him, reminding him of your needs, and keep praying earnestly for all Christians everywhere. 19 Pray for me, too, and ask God to give me the right words as I boldly tell others about the Lord and as I explain to them that his salvation is for the Gentiles too.
