Prayer isn’t just personal—it’s a battlefield duty for every believer. After fastening on God’s full armour (Ephesians 6:10-18), we’re told to stay alert, praying … for all the saints. Like Israel’s soldiers who fought with the welfare of their nation in mind, Christian warriors intercede for fellow believers, asking God to guard and strengthen them. Sometimes, when human strength fails, prayer alone wins the battle because the LORD fights for us. A steadfast intercessor can revive a weary believer. Paul models this wider vision. He prays that Christians grow in wisdom, love, strength and fruitfulness (Colossians 1:9-11; Ephesians 1:17-19; 3:14-19; Romans 1:9-12; Philemon 1:4). In return, he asks them to pray that he might proclaim the gospel boldly (Colossians 4:3; Ephesians 6:19-20). Let’s follow his pattern: put on the armour, persevere in prayer and lift one another so the whole church stands firm, remembering the words of Samuel in our text.
