Jesus said, “While you have the light, believe into the light, so that you may become sons of light” (John 12:36). By believing into Him we become sons with Him as our life and light.
Life and light are seen together in Mark 4. Verses 1 to 20 present the parable of the Sower, sowing seeds of life which grow in us. Verses 21 to 23 present the parable of the lamp, which shines on us and within us. The growing life and the exposing light gradually cause our whole being to match New Jerusalem.
Light and life are also seen together in our Christian living in Philippians 2. Verses 15 and 16 say, “That you may be blameless and guileless, children of God without blemish in the midst of a crooked and perverted generation, among whom you shine as luminaries in the world, holding forth the word of life.”
Here we are children of God with God’s life and we shine with God’s light. While we live and shine in the world, we hold forth the word of life so that others may have opportunity to receive light and life. Their receiving is their entering onto the path to New Jerusalem.
Day by day this life grows and this light intensifies unto fullness in New Jerusalem.
