Believing the right things about Jesus isn't enough. You're not adopted as God's child until you confess and turn away from your wrongdoing and receive the freely offered gift of forgiveness and eternal life that Jesus purchased with his death on the cross. Until you do that, you'll always be on the outside looking in.
