Pause and think about that in terms of you trying to be better, to "be ye therefore perfect", as Jesus' injunction goes. Can we do it all on our own? Heavens no! We don't have nearly enough to get to where we want to be! But when we give all that we have, Jesus takes our meager offering and multiplies it until the job is done. So don't worry if your present situation sucks like having an octopus on your face. Do your best, He'll do the rest.
PS here's a cool talk about Christ's all and our all. Might help illustrate this better.
