Did you really forget what YOU wrote two short posts ago in post 1,179:God will not cast out His children, He will not LOSE a one, He will not take the Holy Spirit from those He has sealed. It is a promise based on HIS faithfulness, not ours. This IS the gospel of the grace of God and those who disagree with it - though they may pay "lip service" by affirming their belief in "justification by faith" - by requiring works in order to stay justified, expose the accursed and false gospel behind their doctrine. It is the SAME thing God used Paul to reveal and, through the illumination of the Holy Spirit, those that hear the voice of the Shepherd of our souls, will surrender to His leading and follow Him and WILL find rest for their souls.
Would it make you feel better if instead of "one and done" I had said "Once save always saved" or "eternal security"?
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
John 10:25-30 Jesus answered them, “I told you, and you do not believe. The works that I do in my Father's name bear witness about me, but you do not believe because you are not among my sheep. My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. I and the Father are one.”
2 Corinthians 1:21-22 And it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee.
2 Corinthians 5:4-8 For while we are still in this tent, we groan, being burdened—not that we would be unclothed, but that we would be further clothed, so that what is mortal may be swallowed up by life. He who has prepared us for this very thing is God, who has given us the Spirit as a guarantee.
So we are always of good courage. We know that while we are at home in the body we are away from the Lord, for we walk by faith, not by sight. Yes, we are of good courage, and we would rather be away from the body and at home with the Lord.
Ephesians 1:13-14 In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.
Ephesians 4:30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
Colossians 1:13-14 He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son, in whom we have redemption, the forgiveness of sins.
Colossians 3:3 For you have died, and your life is hidden with Christ in God.
2Corinthians 1:21-22 Now he which stablisheth us with you in Christ, and hath anointed us, is God; Who hath also sealed us, and given the earnest of the Spirit in our hearts.
For which the Greek, from the Byzantine, is:
2Corinthians 1:21-22 ο δε βεβαιων ημας συν υμιν εις χριστον και χρισας ημας θεος ο και σφραγισαμενος ημας και δους τον αρραβωνα του πνευματος εν ταις καρδιαις ημων
The first word in bold above is “bebaion,” the idea of confirmation, frequently used in commercial settings to confirm a bargain. Which of course makes sense of the remaining terms used here, which are also elements of a secured contract.
The second word in bold above is “sphragisamenos,” being sealed is to be marked by the signature, signet ring, or other unique proof of identity, that we belong to God, and this sealing is done by God, who is the one taking action in this verse. We do not and cannot seal ourselves. We do not, by our own powers, have access to God’s “signet ring.”
The third bolded word above is “arrabona,” and indicates what we might loosely refer to as earnest money, but in Hebrew culture conveys more the idea of a pledge of covenant, a security given as a guarantee that the deal will go through, though we only receive part payment at the beginning. See ערב for the related Hebrew stem indicating “pledge.”
Here’s the link for the exposition on 2 Corinthians 1:21-22.
You said my gospel was "one and done" and now you want to hedge a little? Interesting....do you imagine I have no Scripture to back up what I said?
God will not cast out His children: All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out. (John 6:37)
He will not LOSE a one: "This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. "For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day." (John 6:39,40)
He will not take the Holy Spirit from those He has sealed: In Him, you also, after listening to the message of truth, the gospel of your salvation-- having also believed, you were sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance, with a view to the redemption of God's own possession, to the praise of His glory. (Ephesians 1:13,14)
Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. (Ephesians 4:30)
So, yeah, I proclaim with grateful joy that we are saved by grace through faith and not by our works and that is what gives us eternal security. Our faith and hope is in HIM and not in ourselves. He WANTS us to have this assurance:
Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body, and since we have a great priest over the house of God, let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. Let us hold unswervingly to the hope we profess, for he who promised is faithful. And let us consider how we may spur one another on toward love and good deeds, not giving up meeting together, as some are in the habit of doing, but encouraging one another—and all the more as you see the Day approaching. (Hebrews 10:19-25)
