Answer:
I may only be given but never bought. Sinners seek me but saints do not. (one word).
My first is in riddle but not in little. My second is in think but not in brink. My third is in thyme but not in time. My fourth is in mother but not in brother. My last is in time but no t in climb.
When it comes to me, you go on red and stop on green. What am I?
When I am caught I am thrown away. When I escape you itch all day.
I never was but always will be. No one ever saw me but everyone knows I exist. I give people the motivation to better themselves everyday
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
