Jesus Christ in the Garden of Gethsemane prior to his crucifixion suffered for the sins of all mankind. "And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground." Luke 22:44 Making it possible for all to inherit one of heavenly Father's, "many mansions" John 14:2
The dawn of the first day of the week an angle announced "He is not here: for he is risen..." Matthew 28:6 The message of the first Easter morning. Because of Jesus, everyone will be resurrected.
I know this to true.
