When we are born into this world, it's as if we are dropped into a jungle. The lost souls are the ones who have no idea why they are here. They see only the trees and not the forest of which the trees are a part. They are attracted by the beauties they find in the forest and don't think much about getting out of the forest because they don't know how.
On the other hand, the ones who know Jesus well have all the answers to their existence. They see the entire picture, the whole forest and what's beyond. They are not lured by the local attractions after knowing where they are heading. That's why they live joyfully with peace in their hearts ~ they have been found by God.
