If we claim to have fellowship with Him yet walk in darkness, we lie and do not live out the truth. If we walk in the light as He is in the light, we have fellowship with one another and the blood of Jesus, His son, purifies us from all sin.
How often am I found stumbling around in the darkness? Is it somewhere that I end up in ignorance or on purpose? David prays for protection from his hidden errors and his wilful sins. (psalm 19) Sometimes we get lost down the twisted, darkened roads of sin because we stop paying attention; sometimes we know full well the light dappled narrow path and we avoid it. We do not want to walk in the light because light is scary. Light exposes. Light reveals what we do not want it to. John 3.19-21. The people preferred darkness. And so do I.
To be a child of the day (1 Thessalonians 5.5, Ephesians 5.8) is to have everything on show. Warts and all. It is to confess that we do not have it all together. To confess our failure and our need of him. Much easier to avoid that less trodden path. Much easier to follow our stubborn footsteps. To block out the still small voice. To fall into self-pity and stay there. To give anger a foothold. To indulge jealously. To relish a moment's harsh judgement of another. To do so is to isolate ourselves from God and from each other. To prefer blindness for fear of what we might see in ourselves if the shades were removed.
You, Nic, are a child of light. Once you were in darkness but now you are light in the Lord. Once you belonged to that Kingdom of another but now you live in the glorious light of the kingdom of the One who rescued you. (Colossians 1.13-14)
Act like it.
