It HAS been answered, but the answer just isn't satisfactory, it seems.How does all this make it so that presently holding fast the word that you had preached to me is not the condition in order for me to be presently saved? That is the question that no one seems able to answer.
"1Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, 2by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain." (1 Corinthians 15:1-2 NASB)
When one believes, they POSSESS (hold fast) the word. It's that simple. And, they ARE saved, UNLESS they believed without reason (in vain). Again, very simple.
The whole concept of possessing the Word, and all that goes with it, such as the indwelling of the Holy Spirit, and sealing with the Holy Spirit, etc, are FROM GOD. Nothing we are involved with. We are NOT holding on to the Holy Spirit, which seems to be your position.
