I pray for the living to accept Christ, prior to their appointed dying and then the Judgement.
Praying for those already dead seems a bit late, the die is cast. Heaven or hell, one way or the other.
For those that die knowing Jesus as Savior, Heaven is the destination. Period. Because Jesus’ sacrifice paid all our debts. All. And those debts are cancelled, providing one accepts Him.
So, in summation, Accept Christ while living, because after you die is a bit late.
Only the elect go to purgatory.
So, you believe God is bound to time?
Where is it written that God turns a deaf ear to the pleas of His children when they ask for mercy for the dead?
