Passage
But if a man walke in the night, hee stumbleth, because there is no light in him.
But if a man walke in the night, hee stumbleth, because there is no light in him.
John 11:8 The disciples saide vnto him, Master, the Iewes lately sought to stone thee, and doest thou goe thither againe?
John 11:9 Iesus answered, Are there not twelue houres in the day? If a man walke in the day, hee stumbleth not, because he seeth the light of this world.
John 11:10 But if a man walke in the night, hee stumbleth, because there is no light in him.
John 11:11 These things spake he, and after, he said vnto them, Our friend Lazarus sleepeth: but I goe to wake him vp.
John 11:12 Then said his disciples, Lord, if he sleepe, he shalbe safe.
The verse centers on "light", "walke", "night", and "stumbleth". It is saying that the verse draws attention to "light" and "walke", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "Iesus answered Are there not twelue houres..." into verse 11's "These things spake he and after he...", so "light" and "walke" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "light" and "walke" with trust shaped by these words, not by a vague optimism outside the passage.
