The gift is eternal life. There is no verse that says "eternal life is being in Christ Jesus" and Rom 6:23 doesn't say it.
The passage is about fruit production of believers, not "how to stay saved by works".
No one who has been "marked in Him with a seal, the promised Holy Spirit" can leave union with Christ.
Unless one simply misunderstands or ignores the obvious meaning of GUARANTEEING OUR INHERITANCE and "for THE DAY OF REDEMPTION in Eph 1:13,14.
Can't happen, because of Eph 1:13,14.
The concept of being "in Christ" is taught throughout the Bible. There are 77 verses that I found. Here are a few.
Rom_3:24 Being justified freely by his grace through the
redemption that is in Christ Jesus:
Rom_8:1 There is therefore now no condemnation to them which are
in Christ Jesus, who walk not after the flesh, but after the Spirit.
1Co_1:2 Unto the church of God which is at Corinth, to them that are
sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours:
1Co_1:30 But of him are ye
in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and
redemption:
2Co_5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Gal_3:26 For ye are all the
children of God by faith in Christ Jesus.
Eph_2:6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
Eph_2:10 For we are his workmanship,
created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Col_1:4 Since we heard of your
faith in Christ Jesus, and of the love which ye have to all the saints,
2Ti_2:1 Thou therefore, my son, be strong in the
grace that is in Christ Jesus.
2Ti_2:10 Therefore I endure all things for the elect's sakes, that they may also obtain the
salvation which is in Christ Jesus with eternal glory.
2Ti_3:15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto
salvation through faith which is in Christ Jesus.
Keep in mind that I believe that true believers are kept in the faith by the power of God. Someone who is saved is "in Christ" - see especially II Corinthians 2:17. If you are in Christ - "IF" then you are a new creature. You've been changed by the power of the Holy Spirit. The old is gone, gone, gone. The new is here.
You guys endlessly make the same arguments over and over and over. You never say anything new in these threads. You just repeat over and over the same thing. Don't quibble on words. It's concepts that matter.
There is no word in the Bible for Trinity. Are any of you going to argue against the idea of the Holy Trinity? I hope not. In the same way, eternal life is being IN CHRIST. It's a concept taught throughout Scripture. Look, if a person isn't in Christ, they aren't a new creation and if they aren't a new creation, they aren't saved. It's pretty easy.
Are we eternally saved? Some say no, I say yes. Salvation happens once. Then you are sealed by the Holy Spirit until the day of redemption. Some disagree with my position.
So what. Disagreeing doesn't mean you're right and I'm wrong. How long can you hammer the same nail into a piece of wood?
Why must you be right? You both (I mean both sides of the argument and I'm NOT referring to anyone in particular) must have the last word?
Yes, I'm ranting. Just make your case, then move on. Don't you tire of these endless repetitions?
