Christians have the Holy Spirit in us - but if we have the Holy Spirit in us, we also have the Father and Son alive in us as well. They're all God. But...notice the "IF" condition to this...IF we love Jesus AND show our love by keeping His commands, THEN we will have Jesus, the Father and the Holy Spirit alive in us. If not, not.
One cannot expect to be disobedient and have the blessing of the Godhead alive and active in them. Be obedient, be blessed - and realize the authority you are to carry.
