‘God said, “Let there be light,”‘ (Genesis 1:3 NIV)
Light is important in order that everyone and everything live; people and animals need it to see better to move around and do things, and plants need it in order to grow and survive. Even God realised the importance of light, it was the first thing He created after forming the earth.
David knew the importance of God guiding our way and lighting our paths, and in a song of praise he said ‘O LORD, you are my lamp. The LORD lights up my darkness‘ (2 Sam 22:29 NLT).
The Psalmist knew that we needed God and the light that He gives to us, ‘Lift up the light of your face upon us, O LORD‘ (Psalm 4:6 ESV), ‘The LORD is my light and my salvation‘ (Psalm 27:1 NIV), and ‘that I may walk before God in the light of life‘ (Psalm 56:13 ESV). The Psalmist knew that it was and is God that was lighting his way, and helping him in everything that he does.
When Jesus started preaching, He said to the people, ‘You are the light of the world‘ (Matt 5:14 NIV). Jesus continued to say that we do not light something to shine and then hide it away (Matt 5:15).
When Paul wrote to the Corinthians, he reminded them that, ‘God… … … has shone in our hearts to give the light of knowledge of the glory of God‘ (2 Cor 4:6 ESV); and later continued, ‘How can light live with darkness‘ (2 Cor 6:14); then he reminds us how cunning the devil is, ‘Satan disguises himself as an angel of light‘ (2 Cor 11:14 NLT).
We have been called to live in the light, chosen by Jesus, ‘called you out of darkness into his marvellous light‘ (1 Pet 2:9 ESV).
