some say you are a partaker of Christ even if you don't continue to believe.
Can you point me to that quote?
Sounds like you have a question about the power of the Holy Spirit inside you. Do you believe God is able to keep you safe until the the final day?
Are you thinking that you are "generating" your own faith, and that somehow if you continue to generate faith you will remain saved?
But anyway, the important point of the
Hebrews 3:14 passage is that it says you have truly partaken of Christ if you continue to believe.
It actually says you've become a partaker, not that you have partaken. That also changes the meaning.
There is a new identity you have, a partaker in Christ, and you know that this is true of you as your faith continues to the end. This is a much different message than you are broadcasting.
This new identity, it's not just that, as if you have a different driver's license now. It's that you have an entirely different life. Once you were "alive" because there was fleshy creature with a fleshy mind, and fleshy soul. God would work with these people, providing ways for them to survive until He sent His Son to gather us all up together.
Now, instead of being alive as a fleshy man with a fleshy heart and fleshy mind, we are alive as children of God. Not a life that derives from having a body, but a life that derives from being born of the Spirit, being united with God, indwelt by Him.
So now we are alive in the heavenly realm, and interact through our bodies on this earth. We're to put to death our members upon the earth.
But to think that those members can kill us? We who are alive in Christ Himself? That we may yet die? Jesus Christ Himself said that we would not.
So choose who you will believe.
Much love!
