Jesus answered, “Are there not twelve hours in a day? [i.e., hours of daylight]. If a person walks during daylight, he will not stumble because he can see [by] the sun’s light.
But if he walks at night he [might] stumble, because there is no light [to see by]. [Note: These words have a figurative meaning as Jesus is speaking about His mission in life].
So, Jesus said to them, “The Light will be among you for only a little while [longer]. Walk around while you [still] have the Light [with you], before darkness surrounds you. For the person who walks around in darkness does not know where he is going.
[However], the person who loves his brother continues to live in [harmony with] the light [of God’s truth], and such a person is not the cause of others stumbling [over his example].
