Actually, after receiving the Holy Spirit you can reject the Holy Spirit completely. Good Christian video on the subject: (1) Can You REJECT The Holy Spirit After Receiving Him At Salvation? - Bing video
If one has TRULY been born of the Spirit and SEALED for Christ by the Spirit, then that one could never reject Christ. One - it goes against the Sovereignty of God... Two it goes against the desire of the one "Born" and "Sealed".
