“The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shone” (Isaiah 9.2 ESV).
There are many metaphors to describe Jesus in the New Testament: vine, shepherd, gate, cornerstone, bread, water, word, etc. However, one that Isaiah prophesies in the Old Testament by the inspiration of the Holy Spirit and that Jesus testifies to in the New Testament is “light.” Our world is in darkness because the sins of humanity have separated us from a perfect God. We have been given free will to dwell in the light of Christ, which ushers us into the presence of God, or we can remain in the darkness of separation from our Creator. The world will continue to remain dark until the completion of God’s plans on this earth, yet Christians have an eternal burning light that guides our way. The darker the path, the better because we won’t be able to use our eyes and place faith in our own understanding. As the atmosphere around us gets darker and the corruption of this world peaks, Christians must let go of trust in temporal things and cling tightly to the only Light that truly saves, Jesus. And once others see our peace even in the darkness, they will be drawn to the Light as well.
“When Jesus spoke again to the people, he said, ‘I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life'” (John 8.12 NIV).
