A Permanent Dwelling !
Rom 8:9
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.
The True Believer is secure because if the Spirits permanent dwelling.
This dwelling denotes a special presence, and a permanent one. In fact its an answer to Christ's intercessory prayer for His Church, His Body whom He gave himself for
Jn 14:16
16 And I will pray the Father, and he shall give you another Comforter,
that he may abide with you for ever;
The Spirit never leaves them, they are sealed unto the Day of Redemption
Eph 4:30
And grieve not the holy Spirit of God, whereby
ye are sealed unto the day of redemption.
That word seal means:
to set a seal upon, mark with a seal, to seal
a)
for security: from Satan
in order to prove,
confirm, or attest a thing
To confirm :
to make firm or more firm; add strength to; settle or establish
The Spirit also brings anointing as here
1 Jn 2:27
27 But
the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you,
ye shall abide in him.
Notice John says to these believers, He promises them that they shall abide in Him, that is in fellowship with God and Christ !
