The sun is a type of Christ. He shines in our lives to bring life, light, and warmth. Without Christ we are in darkness. Think of Christ when you read these verses.
Luke 1:78, 79 – the sunrise from on high
Revelation 1:16 – His face was like the sun shining in its strength
Psalm 19:4, 5, 6 – the sun
Malachi 4:2 – the sun of righteousness
