Paul tells us we are children of the light (Eph 5:8, 1 Thess 5:5) and that we do not belong to the darkness or night. Jesus came as light to the world so that we no longer have to live in darkness, but this means constantly embracing the light in order to escape the clutches of the darkness.
God’s word is a lamp for our feet and a light for our path. (Ps 119:105) We need to embrace His word and turn from the things we used to do when we were children of the dark. (Eph 4:17-19) We need eyes that are healthy and will be a light for our lives (Matt 6:22-23), which means choosing not to dwell on things that are part of the dark side of life.
This might mean letting go of certain reading material, TV programmes, social media, pornography, alcohol or other substances which would drag us down paths of darkness and instead committing ourselves to pursuing all that is good and pure. It might mean learning to love people unconditionally and practically so that we are not dwelling in darkness. (1 John 2:9-11). Whatever we do, let go of darkness and follow the Light of the world.
