...” it may simply be an inability to stick to one thing”? Really? How about they are all searching & looking for the Truth?
Where does this requirement to stick to 1 thing come from? Peter said to always be able to give a reason for the hope that lies within us. Paul said if you confess with your mouth that Jesus is Lord, that God raised Him from the dead, you are saved. That’s the reason for the hope that lies within us.
