Christ's greatest prayers were his (sometimes even spontaneous) bold and courageous actions...his doing ...his risking...his participation---He was the man in the arena, actively "daring greatly...not like the conversation-absorbed cold and timid souls on the sidelines who never really have the guts to know victory nor defeat." 

It is often better to burn out by humbly risking the wins and losses of active service than to play it safe by pridefully and contemplatively waiting for the inspiration and the orders.
