Lesson 294

(06-01-12) John 7:37-39, "In the last day, that great day of the feast, Jesus stooandd and cried, saying, If any man thirst, let him come unto me, and drink. He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)

Herein, Jesus promises that those who believe in Him will receive the Holy Ghost, and all the marvelous security and power that comes with it. But, only after He has completed His testimony and received His glorified body.
The Holy Ghost is the spirit of God the Father and the Son. His main purpose to usward is to grant the power of Jesus Himself to those of us who are saved by His blood. He also maintains our salvation throughout eternity. Eph. 4:30, "And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption."~
