Will God say that salvation wasn't what it seemed to be when we get to the eternal abode?
No. At the eternal abode, God will not say that salvation was not what it seemed. The blood of Christ is faithful, and He is faithful. Salvation rests on His faithfulness to keep us, not on how much we love Him or how much faith we have.
Les uses the illustration of a chair: people sit down without inspecting it, trusting it to hold them, and the chair must be faithful. Likewise, Christ claimed to have done everything necessary, and faith is placed in that. Les says when he gets to the eternal abode, God will not say, 'I'm sorry, it wasn't what it seemed to be.' Instead, God will say the blood of Christ is faithful; He is faithful, and that is why we can trust Him. Les sees Paul driving at salvation through the faithfulness of the One who is faithful to keep us, because He loved us and gave Himself for us. A grandson asked if he loved God enough or had enough faith not to be left behind; the point is that it is not how much we love Him, but how much He has loved us.
