Difficult to tie them down on those texts to be honest.
Ecclesiastes does say that but then it also denies the resurrection. Revelation is a vision and the transfiguration is odd.
If you want to confuse them about life after death try Paul's letter to the Philippians. Paul is in chains awaiting trial and he writes about what may happen to him and what he hopes for...
"I eagerly expect and hope that I will in no way be ashamed, but will have sufficient courage so that now as always Christ will be exalted in my body, whether by life or by death. For to me, to live is Christ and to die is gain. If I am to go on living in the body, this will mean fruitful labor for me. Yet what shall I choose? I do not know! I am torn between the two: I desire to depart and be with Christ, which is better by far; but it is more necessary for you that I remain in the body" - Phil.1
It is almost impossible for them to explain why Paul wanted to die and go to be with Jesus.
