Colossians 4:2-4
2 Continue steadfastly in prayer, being watchful in it with thanksgiving. 3At the same time, pray also for us, that God may open to us a door for the word, to declare the mystery of Christ, on account of which I am in prison— 4that I may make it clear, which is how I ought to speak.

Paul was not some super professional Christian going round starting churches and dishing out advice, he knew he needed support and prayer for His ministry. He asks them to give him and his companions opportunities for spreading the gospel and that they would take those opportunities, speaking clearly. Do we pray for our leaders? Do we pray for people that seem to be successful in whatever they’re doing? Do we pray for each other and other churches, other Christians, that we would have opportunities for spreading the name of Jesus? Do we ever say we’ve got no prayer requests, that everything is going fine? We all need pray that God would give us opportunities to show and talk about God’s love and that He would help us take them! It’s a dangerous prayer, but if we don’t want to pray it, maybe we don't fully understand the depth of what God has done for us!
