In Colossians 4, Paul teaches that we should devote ourselves to prayer continually, being watchful in expectation of God's providence, and always giving thanks to Him for answered prayers. Paul then calls us to be wise in our actions when among unbelievers, so that we can make the best use of every opportunity to witness the gospel of Christ. We need to be sure our interactions and conversations with unbelievers are always full of grace ("seasoned with salt"), so that we may know how to respond with a fitting answer to everyone.
