Obeying God in a New, Less-Worried Way

"I know the words 'leave it to God' can be misunderstood, but they
must stay for the moment. The sense in which a Christian leaves it to
God is that he puts all his trust in Christ: trusts that Christ will
somehow share with him the perfect human obedience which He carried
out from His birth to His crucifixion: that Christ will make the man
more like Himself, and in a sense, make good his deficiencies. If you
like to put it that way, Christ offers something for nothing: He even
offers everything for nothing. In a sense the whole Christian life
consists in accepting that very remarkable offer. But the difficulty
is to reach the point of recognizing that all we have done and can do
is nothing. What we should have liked would be for God to count our
good points and ignore our bad ones…if you have really handed yourself
over to Him, it must follow that you are trying to obey Him. But
trying in a new way, a less worried way. Not doing these things in
order to be saved, but because He has begun to save you already." --C S
Lewis, Christian Behavior
