How to get out of Purgatory

Jesus willingly died for the believers sins; He died in our place to pay the debt that we could never pay. Who his own self bare the believers sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed (I Peter 2:24). How devastating it is that Catholics trust in a place not mentioned in Scripture, but which they call Purgatory. They are taught to trust that somehow they can through suffering be purified enough to achieve the holiness necessary to enter heaven.
