In the natural realm we have ways to make the invisible visible. The infrared camera can take photographs on the blackest nights. Police use radar helicopters and can find a thief in the dark even under trees. In the spiritual realm nobody need to walk in darkness. There is a way ‘to see Him who is invisible’ (Heb 11,27). The instrument is faith. It is our infrared. We have eyes to see and can walk in the ignorance and blackness of our world with confidence, as in daylight. Believers are ‘children of the day’. ‘We walk by faith, not by sight’ (2 Cor 5,7). God bless you.
