But were they ever saved to begin with?
Brother, if you don’t know the answer to that question, why are you arguing so much?
How can a person be “in Christ” and not be saved?
For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. 1 Corinthians 12:13
If a person is “in Christ” it’s because the Spirit has baptized you into Christ.
You are now one with Christ.
But he who is joined to the Lord is one spirit with Him.
1 Corinthians 6:17
If you are in Christ, you are joined to Him, and are one spirit with Him, being one spirit with eternal life.
You have been made to drink of the Spirit of life in Christ.
