I have heard some people complain that if Jesus was God as well as man, then His sufferings and death lose all value in their eyes, "because it must have been so easy for him." ... The perfect submission, the perfect suffering, the perfect death were not only easier to Jesus because He was God, but were possible only because he was God. But surely that is a very odd reason for not accepting them? ... If I am drowning in a rapid river, a man who still has one foot on the bank may give me a hand which saves my life. Ought I to shout back (between my gasps) "No, it's not fair! You have an advantage! You're keeping one foot on the bank?" That advantage - call it "unfair" if you like - is the only reason why he can be of any use to me. To what will you look for help if you will not look to that which is stronger than yourself?
