Would you know what signs to look for? Do you know the difference between the living and the dead? If you don't know that, how could you possibly know if the Christian dead were being raised to life by Divine decree and ascending bodily into heaven right in front of your eyes as Jesus emerges from the clouds that have obscured him from sight for the past several thousand years?
In all my life I have NEVER encountered anything that I deemed to be supernatural. All those things you mentioned may have occurred but until I have a reason to believe I'll maintain my skepticism about all things supernatural and continue to believe that no one knows more about the subject than I do (which is of course nothing).
I am not talking about anything supernatural unless you would consider right wing religious fundamentalist gibbering wackos being restored to a sober and rational mind a miracle that amounts to the dead coming out of their graves.
I must have been mistaken. What are the 'signs' you spoke of?
The signs that God is intimately involved in human affairs? As I said , the dead rising out of their graves, coming to life, and ascending bodily into the kingdom of heaven while others who set aside the laws of God continue to die the death while slowly descending into the cacophony of the pit, kicking and screaming.
for your entire life, in fact for thousands of years, all of this has been happening right here on earth in full view of believers and unbelievers alike.
And, whatever you believe or don't believe, if you don't know the difference between the living and the dead you will see nothing even if the risen dead were standing all around, right in front of you, watching..
