You can't base all your theological beliefs on one scripture.
Those who are raised with Him will appear with Him IF they are still raised at the end of their life.
I see a great many Scriptures which either teach this very thing, or agree with that understanding.
And even so, just that one passage is not wrong.
You're assertion is that we should introduce a condition to be met that does not appear in the verse. It sounds good, and it seems to make sense, but the net result is to introduce doubt where God gives certainty.
It seems that your presupposition is that somehow, some who are raised with Him will not in fact appear with Him, and therefore, this additional condition is required.
And it equally seems that this passage carries it's own supposition, that your additional condition is not needed, and in fact, this is a thing that won't happen.
And many other Scriptures agree. Peter tells us it's God Who is keeping us by His power through faith. This is to say that the faith in us that carries us through this life is God's power. He will not fail us.
They all state that we will be saved IF we hold firm till the end.
This is of course true! If you hold you confidence stedfast to the end, this means that you had become a partaker of Christ. If you do not, that means you had not actually become a partaker of Christ, even if you, or someone else thought you had.
Why is this important? The true children know. The Spirit testifies with our spirit that we are the children of God. And the true children need to understand that all our concerns over all our problems will be addressed with Jesus comes, when we see Him, because we will become like Him.
And knowing that this is our new future, knowing that, he who has This Hope purifies himself, even as He is pure.
Knowing . . . not wondering . . . knowing that we will be like Him then means we purify ourselves now. If you do the one, you do the other.
And so I want to point people to a full trust in Jesus to accomplish all that is needed in your life, and you can just focus on enjoying His fellowship in this moment. If you are doing that, whatever else comes in your life, you will respond from the position of, I'm here, my Creator is here, and He loves me so much! Thinking about this passage, listening to that hymn, talking to Him, listening to that still voice, as we move through our day together. I love Him so much! Any issue, any question, difficulty, whatever, Jesus? What do we do? And the answer is there, or the answer waits. And either it goes the way I think I want, or it goes some other way, but Jesus is here, and He loves me so much!!
This doesn't come when yo are concerned that your eternal life could be ripped away from you - call it what you want, but the net result is fear.
Fear that maybe one day I'll just go too far.
Fear has torment, and the one who fears has not been matured in love. If our hearts condemn us, God is greater than our heart. He's not bound by our limitations, instead, He knows all things. He knows what we don't know, what He's going to do for us, but He's told us, so we can know, if we will only believe it's real.
Much love!
