Have you ever been in the house at night and suddenly the lights go out? There you are, standing in the pitch dark, desperate for a light. Or you hear a noise outside and you know you need to go investigate but its pitch black. To stay safe, you arm yourself with a flashlight.
Gods word, (the Bible) says in John 14:6 "I am the way, the truth and the light. No one comes to the Father but through me" This was Jesus speaking.
And in psalm 27:1 it says "The Lord is my light".
Truly throughout scripture God is referred to as the spirit of truth and truth is often interpreted literally as "light". When you walk in the spirit, you walk "in the light". You are a light that shines in the darkness. So think about that next time you are caught in the darkness without a light ie: truth.
it is always good to be prepared....in spirit AND in truth.
