We are in quite a unique struggle.  When a person is born again of the spirit of God, he receives many things, most importantly the spirit of God.  In our daily walk we find that there is a conflict within us. The habits of the old nature still fight with the new creation within and we are called upon to put off the old and put on the new. We already have victory in Christ but it benefits us moment by moment to renew our minds and allow the transformation to evidence itself in the senses world.  We are a completely new creation in Christ and we can walk in that reality as we recognize it moment by moment.  We have a new identity, which identity do you relate to?
