It’s not until the righteous in safely then God will unleash His Judgement on the earth. When does the rapture happen? Do all who proclaim Christianity go in the rapture?
Rapture and second coming are two separate events. Trinity is a solid doctrinal concept. Jesus is thinking of us and sending us gifts.
God will regather the members of His church. Watch for the signs Jesus told us to watch out for. We are in the dispensation of Grace. There is a faith that does not save.
