As part of the restoration, the Lord often makes a point to say that He uses the weak and simple.  Certainly Joseph Smith was part of that, an unlearned school boy used to bring God's kingdom back to the earth. However, God also needs you and I in His great work. Often times we don't feel like enough. But never forget that we worship a God who is the great multiplier! He can take our weak and simple efforts and make them more. Who we are and our efforts combined with God's power is more than enough!
