May God have mercy on your soul.
So show how this doctrine is supported by scripture. Please no cut and pastes from Catholic apologetic sites:
The Catholic doctrine of intercession and invocation is set forth by the Council of Trent, which teaches that
the saints who reign together with Christ offer up their own prayers to God for men. It is good and useful suppliantly to invoke them, and to have recourse to their prayers, aid, and help for obtaining benefits from God, through His Son Jesus Christ our Lord, Who alone is our Redeemer and Saviour. Those persons think impiously who deny that the Saints, who enjoy eternal happiness in heaven, are to be invoked; or who assert either that they do not pray for men, or that the invocation of them to pray for each of us is idolatry, or that it is repugnant to the word of God, and is opposed to the honour of the one Mediator of God and men, Jesus Christ (Sess. XXV).
He already has. Through the finished work of His SOn Jesus Christ, who ONCE for ALL paid the price for sin.
I am free from trying to earn my salvation through my worthless works and filthy flesh.
Jesus paid it all.
Praise God.
