Here is the Greek to English reading of
Luke 23:43. The words Yeshua said to the thief according to the Pocket Interlinear by Jay Green Sr. and the NKJV Greek Interlinear.
And Jesus said to him Assuredly I say to you today you will be with me in Paradise.
The commas are added by men and not inspired. So you can see once that is understood Yeshua is telling the man
TODAY I tell you you will be with me in Paradise.
That makes more sense with the weight of the scriptures and also as directly answering the thiefs request which was:
Lord remember me when you come into your kingdom.
He simply asked the Lord after he came into the kingdom to remember him.
And so the case agaist immortality/eternal life apart from the resurrection continues to grow.
