God is light – there is no darkness in Him, and we are called ‘children of light’ (1 Thes 5:5; 1 Jn 1:5). God’s Kingdom is a kingdom of light indicating purity, openness, holiness and love as opposed to Satan’s dark Kingdom of sin, deception, uncleanness and lust.  Once we walked in darkness but now we walk in God’s light enjoying fellowship with each other and Jesus Himself, provided we deal with any sin that we commit (Eph 5:8; 1 Jn 1:5-7, 2:10,11).  Am I a good advertisement or recommendation for Him – do people see Christ in me?  Are my words and actions a clear reflection of what Christ’s would be?

Jesus said, “I am the light of the world. Whoever follows me will never walk in [spiritual] darkness” – His life-giving light is available for all mankind (Jn 1:4,5, 8:12,  9:5, 12:46). He came to show the way to God for in His light we see how sinful we are and in need of saving, and can receive that light of His eternal life.  Is He the light of my personal world? Do I respond appropriately, by changing my behaviour when by the Holy Spirit He points out areas that need to made right?

God’s Word is a light for our path (Ps 119:105). As we read, study and apply its teachings and principles it will guide us and we will not stumble off the path to heaven. It is when we rebel, insisting on stubbornly going our own way, against what we know is the truth,

Am I truly walking in the light?

that we step away from the light. Walking in the dark without a light or in rebellion is when we stumble (Jn 11:9,10).

We are to be lights for Jesus, shining in this sinful world.  The purpose of light is to illuminate so don’t hide your light but let it shine (Mt 5:14-16; Eph 5:13,14). Put on the ‘armour of light’ which is right living, this can be used by God to turn people from darkness to light (Act 26:18; Rom 13:12).

Light can be represented by fire, such as the pillar of fire that led the Israelites through the wilderness, indicating God's presence, protection and guidance (Ex 13:21,22).
