Your light could be shining but the moment you meet somebody who is in the darkness your light can be extinguished. God saw it fit that we must have light before we were created. Genesis 1:3 Then God said, “Let there be light”; and there was light. When you are in the dark look for light. Sometimes we can see that we are in darkness but we justify. 2 Corinthians 6:14 Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? The scripture does not mean we must not have relationship with them but don’t partake in their evil ways. Our love for them must attract them to Christ. It is important to see to it that nobody switch off your light else you’ll have fractures.
