Light is one of the great Johannine words that occurs no fewer that twenty-one times in the fourth gospel. It is one of the two key words upon which John builds his testimony of Jesus. John describes Jesus as a light that has come into the world to light the life of every man (John1:9). Another one of John’s key words is darkness. John saw a darkness in the world that was very real and very hostile to the light. This darkness represents evil. Sinning man loves the darkness and hates the light, because the light exposes their wickedness. John takes these two themes and shows their natural opposition. He portrays a universal battleground where the forces of dark and light are arrayed in an eternal conflict. The light shines in the darkness and the darkness cannot extinguish it (John1:5). The darkness seeks to eliminate the light of Christ—to banish it from life, but the light will not go out!
This conflict is played out in the pages of sacred history. The Old Testament lets us witness everything from individual struggles with evil for the soul of a man to heavenly warfare for the soul of a Nation. In the New Testament this conflict emerges with intensity around the cradle of the incarnate Christ as the forces of darkness unleash Herod’s sword in a futile attempt to eliminate the light. The ultimate battle, however, would unfold at Calvary. The rulers of this age and the powers of darkness thought if they could only nail Christ to the cross that darkness would win once and for all. They thought the crucifixion of Christ would be the ultimate defeat and their final triumph. In fact, it proved to be just the reverse. Out of the darkness of his death came the blinding light of His resurrection victory. The light of this good news exploded out of the confines of Palestine and across the known world like a quickly spreading flame until, in a few decades, the gospel had impacted every major population center of the Roman world.
The powers of darkness responded with persecution and torture. But wild beasts and boiling oil couldn’t put out the light and the blood of the martyrs only fueled the flame. When persecution from without did not succeed, the forces of darkness turned inward and awful darkness settled down over the church. But out of the heart of that darkness, reformation fires began to burn and the light prevailed. Every counter move by the forces of darkness to extinguish the light only brought revival fires that would break out and save lives, transform nations, and change the course of history.
The darkness has used all sorts of political ideologies, human philosophies, and false religions to advance its cause. But the light always breaks through to enlighten the mind and liberate the hearts of men. As you gather with friends this Christmas season, light a candle and lift your voice in praise for light has come into the world and the darkness has not and will not overcome it!
