Manning is a good author. Some gleanings:
"Live in the now-here. When you walk, walk. When you wash dishes, wash." Don't be spending that time thinking and worrying of all the bazillions of things you must do later. Just enjoy the walk, and trust that God has everything in the future taken care of.
p163- "In everything, give thanks [whether good or bad]." 1 Thes. 5:18
p178- "You will trust Him to the degree that you know are loved by Him." After experiencing Him, you come to love and then trust Him.
