Sorry to post about the second coming, but I am in terror he's here and my last mortal sin wasn't forgiven. A lot of scripture indicates that his second coming is marked by a blood moon. It also indicates that he is seeen as like a fire/ a bright light that lightens up the sky . That he puts a mark on the hand of the wicked. It says all eyes will see him ( but will they recognise he is Jesus If he looks like the sun) ? Who knows
The second coming is a long way off so strike that one off the list of concerns. Did Jesus suffer and die a painful death for you to doubt his mercy? Your doubt comes from a lack of trust or from the evil one, the accuser. 'Jesus I trust in You' is powerful prayer if you say it and believe it.
