Matthew 7:7 "Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.After years of addiction to alcohol and drugs, he died and shown heaven, was given another chance.
He was clean for several months, but went back to his addictions, harder.
The next thing he knew he was on the edge of hell being tortured by the devils. He called on God asking for forgiveness. And he was forgiven.
ASK GOD FOR FORGIVENESS WHILE YOU'RE STILL ON EARTH.
Matthew 6:15 But if you do not forgive others their sins, your Father will not forgive your sins.
