Yes, but what do we mean when we talk of God helping us? We
mean God putting into us a bit of Himself, so to speak. He lends us a little
of His reasoning powers and that is how we think: He puts a little of His
love into us and that is how we love one another. When you teach a child
writing, you hold its hand while it forms the letters: that is, it forms the
letters because you are forming them. We love and reason because God loves
and reasons and holds our hand while we do it. Now if we had not fallen,
that would be all plain sailing. But unfortunately we now need God’s help in
order to do something which God, in His own nature, never does at all-to
surrender, to suffer, to submit, to die. Nothing in God’s nature corresponds
to this process at all. So that the one road for which we now need God’s
leadership most of all is a road God, in His own nature, has never walked.
God can share only what He has: this thing, in His own nature, He has not.
But supposing God became a man-suppose our human nature which can
suffer and die was amalgamated with God’s nature in one person-then that
person could help us. He could surrender His will, and suffer and die,
because He was man; and He could do it perfectly because He was God. You and
I can go through this process only if God does it in us; but God can do it
only if He becomes man. Our attempts at this dying will succeed only if we
men share in God’s dying, just as our thinking can succeed only because it
is a drop out of the ocean of His intelligence: but we cannot share God’s
dying unless God dies; and He cannot die except by being a man. That is the
sense in which He pays our debt, and suffers for us what He Himself need not
suffer at all.
