I do...the 'sanctity of the believer' comes to mind. An individuals salvation belongs to Christ....He knows who are His and vice versa....Either they are "sealed" in Him or not...there is no middle ground....those who are KNOW they are His....it's really that simple. Scripture was written that we may KNOW we are His....not second guess His words.
Certainly "works" follow, they cannot help to be so as the individual is a "changed" man. But works are not a 'requirement' which affects ones salvation.... as the thief on the cross had no time or opportunity but to acknowlege Christ's sinlessness and admit his own sin...Jesus took Him with Him that very day.
But in the catholic faith it is my understanding it's a sin to acknowedge you KNOW your salvation is assured. ..and that flys in the face of what otherwise is clearly stated.
OK, I will get back to you on that when I have more time. There are four scriptures I want to ask you about. One is when Jesus said to one who had healed the sick and cast out demons in His name, “I do not know you”. Another has to do with Paul finishing the race. Essentially, why do we need to develop a relationship with Christ if eternal life with God is already assured?
