It seems that Thurman has segregated humans into three categories:
1) those who have a vision and the abilities and opportunities to achieve that vision even through trials.
2) those who have a vision but the way is paved with difficulties that weigh them down.
3) those to whom a vision never comes. Their road is neither rough nor smooth, no sudden turns nor surprises.
Thurman blesses them all asking God to provide for each person, according to their need. “Pour out the riches of Thy grace that none need be alone and none may seek another’s light.”
We’re all given our own path to travel. Some will be easier than others. Some will take the light and run toward their vision. Others will try to run without light and stumble along. Still others will be content not to run for a vision. All are good. None are better than the other. There is no reason for harm. God loves each one just as they are.
