St. Catherine of Siena says: “Praise be to Jesus.”
“I desire that you understand the inner elements of trust. When the Lord asks a soul to trust, the heart is then set adrift in a period of waiting,waiting to see how the Lord will act and what the Divine Will desires. At times, the soul may feel abandoned,not knowing how long his wait upon the Lord will be. In a sense, this is much like Purgatory, in that the Poor Souls do not know how long they must wait for their deliverance into Eternal Glory.”
“So it would be wise to ask the assistance of the Poor Souls whenever God tells you to trust. They will help you wait upon the Lord, and you can pray for their patience during their time of waiting. Yes, trusting is much like a little Purgatory on earth.”
