I think this is where most of us differ with your doctrine.
We are in a covenant relationship with Christ, through faith in Him.
We are joined to Him as a man and woman are joined through covenant relationship.
Your whole theory is based on the fact that it's impossible to become divorced, or become disconnected from Christ, to whom we are joined.
5 Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not! 16 Or do you not know that he who is joined to a harlot is one body with her? For “the two,” He says, “shall become one flesh.”17 5 Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make
them members of a harlot? Certainly not! 16 Or do you not know that he who is joined to a harlot is one body
with her? For “the two,” He says, “shall become one flesh.”17 But he who is joined to the Lord is one spirit with Him. 1 Corinthians 6:17
- But he who is joined to the Lord is one spirit with Him.
This is illustrated in many ways in scripture by the Lord Himself, using the natural things of this earth, earthly things, to reveal a spiritual or heavenly reality.
As long as we are joined to the Lord, we are joined to the Spirit of Life in Christ Jesus.
If we become disconnected from Him, then we no longer are joined to the life of His Spirit; The Spirit of eternal life.
“I am the true vine, and My Father is the vinedresser. 2 Every branch in Me that does not bear fruit He takes away; and every
branch that bears fruit He prunes, that it may bear more fruit. 3 You are already clean because of the word which I have spoken to you. 4 Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me.
5 “I am the vine, you
are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. 6 If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned. John 15:1-6
- Every branch in Me that does not bear fruit He takes away;
- If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned.
You seem to dismiss this an an unimportant "agricultural metaphor", when Jesus is teaching us a life or death principle.
Just as a branch is dependent upon the Vine that it is connected to, we also are dependent on Christ to provide us eternal life, that is only found in Him.
Apart from, and disconnected from Him, we do not have eternal life.
This connection to Him comes from believing.
I have asked many times for you to provide the scripture that teaches us, a person who believes for a while, then
does not believe any longer, still has eternal life.
No one who is separated or cut off from Christ has eternal life in and of themselves.
13 But the ones on the rock are those who, when they hear, receive the word with joy; and these have no root, who believe for a while and in time of temptation fall away. Luke 8:13
- who believe for a while and in time of temptation fall away.
Where is the scripture that shows us,
those who do not believe any longer have eternal life?
