When we become a child of God through faith in Christ Jesus as Lord and Savior, God at that time sends the Holy Spirit to live within us and the indwelling Holy Spirit imparts the nature of God to us. Unfortunately, however, our old sinful nature is still present; it's not done away with at conversion (when we get saved).

As a child of God we have two natures (the old sinful nature and the new nature of God). As we draw closer and closer to God (as we live more and more by the leading of the Holy Spirit in our lives) we will see less and less of the sinful nature manifesting itself in our lives. In this life, however, we will never be above sin but we are not to allow sin to control our lives, to master us. A child of God should always remember who they are.
