Van Morrison’s song “Bright side of the road” encourages us to move from the dark side (of the street) to the bright side (of the road). The illustration of moving from the dark to the light was used by the apostle Paul many years beforehand, in his letter to Christians in and around the ancient city of Ephesus: “For once you were full of darkness, but now you have light from the Lord. So live as people of light!” (Ephesians 5:8, NLT) Paul’s encouragement to the believers can be summarised under three headings: You have been called out of darkness Leave the dark side and be enlightened by Christ Walk as children of light If Christians have left the darkness of unbelief and sin behind (in principle while they are striving to do so in practice, as they wait until going to be with the Lord when they will have left it behind completely), if they have crossed over to the bright side, they ought not to walk in the dark side any longer.
