The Disciples Sealed in Christ at Salvation
Up to this point the disciples knew the Holy Spirit because Jesus had told them "for he dwelleth with you." 50 But since their names had already been "written in heaven" 51 when Jesus appeared to them upon His return and breathed upon them, they "received him, [and] to them gave he power to become the sons of God." 52
Therefore, because they had been "born of the Spirit", 53 the prophecy that they would receive the Holy Spirit 54 was fulfilled since they now knew Christ no more "after the flesh" 55 but "in the Spirit." 56
"If any man have not the Spirit of Christ, he is none of his." 57 This is the message of salvation. "By one Spirit are we all baptized into one body...and have been all made to drink into one Spirit." 58 "There is one body, and one Spirit,...one Lord, one faith, [and] one baptism." 59
When you are confronted with the baptism of the Holy Spirit you must know what you have to start with at salvation so you can judge what it is that is to be added and how it relates to your position as a believer.
