Ok I noticed you didn’t address my question about why Paul said they were running so well in verse 7. Also he refers to them as brethren. Another thing is those who were never in Christ are never referred to as brethren and Christ Himself says that He never knew such people. Furthermore Paul tells them to walk in the Spirit in verse 18 so apparently they were believers otherwise he wouldn’t be telling them to walk in the Spirit he would be telling them to believe because they can’t walk in the Spirit until after they believe.
Scripture proclaims believers are RIGHT NOW FORVER SEALED by God via His Holy Spirit.
Scripture disagrees with your interpretation, actual Greek to English translators (below) disagree with your interpretation. It's now a hard choice (for me) who has it right. You have it wrong!
The Holy Spirit is the new covenant Seal/promise from Christ. His blood has purified the believer & takes away every one of there sins Past-Present-Future!
Vine's Expository Dictionary of New Testament Words: definition - SEAL
English "seal" = Greek "sphragizo" context as a verb - Strongs ref #4972
(d) ownership and security, three indications are conveyed in Ephesians 1:13 , in the metaphor of the "sealing" of believers by the gift of the Holy Spirit, upon believing (i.e., at the time of their regeneration, not after a lapse of time in their spiritual life, "having also believed," "after that ye believed;" the aorist (TENSE) participle marks the definiteness and completeness of the act of faith); the idea of destination is stressed by the phrase "the Holy Spirit of promise" (see also Ephesians 1:14 ); so Ephesians 4:30 , "ye were sealed unto the day of redemption;"
(MY NOTE: Vines translators define SEAL (Eph 1:13-4, 4:30) as: OWNERSHIP & SECURITY. Christ's FOREVER SEALING (Jn 14:16) GIFT (Acts 10:45, 11:17) of His indwelling Holy Spirit (Rom 8:11, 1Cor 3:16, 2 Tim 1:14). Given upon/at the moment Christ JUSTIFIES/seals (Rom 3:24-26) the believer, thru FAITH. Placed in the Lords sin atoning work. VINE's translators say: This SEAL (aorist TENSE participle) marks the definiteness & completeness of the act of faith. Jesus is the author & finisher of our faith (Heb 12:2)
Find here the verses Vines translators cite as applicable to the word: SEAL:
Eph 1:
13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Eph 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Vine's Expository Dictionary of New Testament Words - [ 1,,G728, arrabon ] (Noun) EARNEST:
originally, earnest-money" deposited by the purchaser and forfeited if the purchase was not completed, was probably a Phoenician word, introduced into Greece. In general usage it came to denote "a pledge" or "earnest" of any sort; in the NT it is used only of that which is assured by God to believers; it is said of the Holy Spirit as the Divine "pledge" of all their future blessedness, 2 Corinthians 1:22; 2 Corinthians 5:5; in Ephesians 1:14, particularly of their eternal inheritance.
(MY NOTE: EARNEST denotes a DEVINE PLEDGE. The giving of the Holy Spirit as the DIVINE PLEDGE. An ASSURENCE given by God, of all their future blessedness, particularly of their ETERNAL LIFE inheritance. This promise read below: God HAS GIVEN/DONE DEAL!)
Find here the verses Vines translators cite as applicable to the word: EARNEST
2 Cor 1:22 Who hath also "sealed us" & "given the earnest" of the Holy Spirit in our hearts
2 Cor 5:5 God, who also hath given unto us the "earnest" of the Spirit
Eph 1:14 Which is the "earnest" of our inheritance until the redemption of the purchased possession
(MY NOTE: Christ's Holy Spirit, given to every believer at the moment of conversion/when the believer is SEALED. Is God's proof/guarantee of ownership & security. Christ's pledge/promise And He's completely trust worthy & proved it on the cross. That believers are a purchased (with His perpetually cleansing God blood sacrifice) possession & HAVE BEEN GIVEN/DONE DEAL/ETERNAL LIFE. If one can loose this GIFT (thru sinning/non-abiding WHATEVER) then it isn't ETERNAL. JJ
