Colossians 3:16-17 – Let the message about Christ, in all its richness, fill your lives. Teach and counsel each other with all the wisdom he gives. Sing psalms and hymns and spiritual songs to God with thankful hearts.  And whatever you do or say, do it as a representative of the Lord Jesus, giving thanks through him to God the Father.
In these verses there are three simple but powerful thoughts.
1. Be filled with Christ – Verse 16 says to let the message of Christ fill your life. The message of Christ’s love, forgiveness, salvation, mission and Lordship is huge. Ponder it. Meditate on it. Surrender to it.
2. Encourage one another – The second part of verse 16 tells us to encourage your Christian brothers and sisters. We do this as we teach and counsel one another, and when we come together in fellowship.
3. Represent Christ – Verse 17 reminds us to be Christ’s representative in all we do and say. This is about living a life worthy of Christ and bringing honour to God. Matthew 5:16 reminds us to let our lights shine. Represent Christ and your faith well each day.
When we do these things it will show that we are filled with Christ. Then His light and His love with overflow and touch the people around us. And when we do this, it brings glory to God.
