Christ is ‘the bright and morning star.’ He is that light that came into this world of darkness, which heralds the coming of the eternal day. Satan before his fall was called Lucifer, the morning star, but the glory of his light was extinguished by pride and he became the ruler of the kingdom of darkness. Christ alone may rightly be called the morning star, and believers seeing him know that the eternal day is not far away. He is that bright star which becomes visible across the whole world as the gospel is being preached to all nations. He is seen wherever men and woman hear the good news and put their trust in him as the Saviour of the world. Christ speaks of what he is in the sight of a fallen world because this book is given to the churches still engaged in the struggle on earth. He is that bright star which none can confuse with any other star. The coming of this star is not yet the dawn, but it promises the dawn soon afterwards. So the Light of the world heralds the coming of that day that will bring everlasting blessing. They hold out against the darkness, continuing to shine though all around them is darkness, and just as the darkness did not extinguish the true Light, so it does not extinguish the light of a single believer who has truly been born from above. They will not deny him; they maintain their witness; they continue to walk separated from the world; they put on the armour of light and cast off the works of darkness.
