If you want to wake up your JW relatives try challenging them with this series of Bible quotations:
Acts 1 v 11
Men of Gal′i·lee, why do you stand looking into the sky? This Jesus who was taken up from you into the sky will come in the same manner as you have seen him going into the sky.”
John 20 v 19-20
When it was late that day, the first day of the week, and the doors were locked where the disciples were for fear of the Jews, Jesus came and stood in their midst and said to them: “May you have peace.”+ 20 After saying this, he showed them his hands and his side.+ Then the disciples rejoiced at seeing the Lord
It was the same damaged body that had been wrapped in linen and left in the tomb.
Matthew 28 v 6
He is not here, for he was raised up, just as he said.+ Come, see the place where he was lying
In other words, he got up and walked away.
Matthew 24 v 23-26
Then if anyone says to you, ‘Look! Here is the Christ,’+ or, ‘There!’ do not believe it.+ 24 For false Christs and false prophets+ will arise and will perform great signs and wonders so as to mislead,+ if possible, even the chosen ones. 25 Look! I have forewarned you. 26 Therefore, if people say to you, ‘Look! He is in the wilderness,’ do not go out; ‘Look! He is in the inner rooms,’ do not believe it.
In other words he won't be hiding anywhere. When he comes back it will be obvious.
