mp, If I said on friday I would be traveling to your place and I would be returning on sunday to my place I could say I was spending three days with you. We would both agree I would spend the whole of saturday with you but what about the other two days? If I spent 1 hour on friday with you and two hours on saturday with you haven't I still been with you for three days?
Mp , Rea 1 corinthians 15 verse 50 -55 it says there we 'will be changed in a flash , in the twinkling of an eye'
