I have a friend whom I visit, he is housebound ,he is aged 91,I have known him for a long time,he has a wonderful testimony of how God saved him many years ago in Dublin's fair city.He was brought up in a Roman Catholic family, most people in Dublin in fact in Southern Ireland were Catholic's.His brother became a priest,and he himself joined a religious order for a while.He went to Mass and confession regularly, but for all his religiosity he had no peace,no assurance of his sins being forgiven.Let me digress and ask why he had no assurance of salvation.The Mass is seen as Christ being sacrificed again and again,so it goes on unending.Christ came to put an end of continual sacrifices.In Hebrews 10 we are told that they were only a shadow of the good things that were coming through Christ .The sacrifice of animals God did not desire they could not effectively deal with sin,we are told that God had no pleasure with blood offerings and sin offerings.So Christ in obeying the will of God,offered Himself up as one sacrifice for sin never to be repeated again. (Hebrews 9 v 27-28)So it was as my Friend read the scriptures he realised that Christs one time offering would effectively deal with His sin.
'Not all the blood of beasts,
On Jewish altars slain,
Could give the guilty conscience peace,
Or wash away the stain.
But Christ the heavenly Lamb,
Takes all our sins away; (Words Isaac Watts)
