"the promise" was not the person of the Holy Spirit. The promise was supernatural power/gift FROM the Holy Spirit.
May I submit that we have received the "person" of the Holy Spirit and the gift? And here we are going to have to mention the Triune God.
Eph 4:30
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Gen_6:3, Gen_6:6; Jdg_10:16; Psa_78:40, Psa_95:10; Isa_7:13, Isa_43:24, Isa_63:10; Eze_16:43; Mar_3:5; Act_7:51; 1Th_5:19; Heb_3:10, Heb_3:17
whereby: Eph_1:13
the day: Eph_1:14; Hos_13:14; Luk_21:28; Rom_8:11, Rom_8:23; 1Co_1:30, 1Co_15:54
Rom 8:9 But ye are not in the flesh, but in the Spirit,
if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
3) "If so be the Spirit of God dwells in you,"
(eiper pneuma theou oikei en humin) "Since the Spirit of God dwells in your all;" both as individuals and the church which he indwells and empowers, Joh_16:7-11; 1Co_3:16; 1Co_6:19-20; Eph_4:30-32.
4) "Now if any man have not the Spirit of Christ," (ei de tis pneuma Christou ouk echei)
"But if anyone has, holds, or possesses not the Spirit of Christ," when one is, born again, or born of the Spirit, he is made a partaker of God's divine nature, Joh_3:6-7; Joh_6:63; 2Pe_1:4; 1Jn_4:13.
5) "He is none of his," (houtos ouk estin autou)
"This one (this kind of one) is not of him;" One without the indwelling of the Holy Spirit, is unsaved and a child of the devil, does not belong to Christ, (except by right of creation) as all men do, Eze_18:4; Mal_2:10. But through the carnal, fleshly, inherent, enmity of the old nature against God, one is void of the Holy Spirit, does not have any preparation to enter heaven or belong to Christ; Eph_2:12; Eph_4:18.
Mere dorean, or the INDWELLING of the Holy Spirit--and Christ IN us John 17?
Joh 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
Joh 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
3) "That he may abide with you forever."
(hina he meth' humon eis ton aiona) "In order that he may be with you all forever, - into the age, the heavenly age, when you come to my Father's house, as my bride, into the ages, Eph_3:21; Joh_16:7; Joh_16:13-14. This is something Jesus could not do forever in His bodily presence. This paraclete (comrade or companion) is also referred to as or translated "advocate," as a person called to one's aid or assistance, especially in courts of justice, to represent or defend one, 1Jn_2:1.
Rom 8:10
And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
Rom 8:11
But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Can you accept this?
