Do you really believe The Creator of the Universe needs or even desirtes your flesh works to put HIS LIFE in your human spirit? Is your Catholic Org god so weak that he would need your help? Does your Jesus only have insufficient worth to guarantee He has paid your penalty for sin? Pssst, there is no such thing as purgatory where you can pay for your sins with your flesh or anything else, but that only applies to those who are trusting in The Lord Christ to be their sufficient Savior.
Salvation comes by faith ALONE in Christ Alone. You cannot add and are not required to add anything to the work the Supreme Creator of the Universe has done on your behalf. You do not and will not deserve ANY glory for the salvation GOD gives to you by HIS GRACE.
Thankful for completed work Jesus did on the cross! And the victory he gives!
