Exactly my point. The only way to know that you are "saved" is to walk the walk. You can be deceiving yourself.
Not so. There are many who will say to Jesus, Lord, Lord, did we not perform many wonders, etc. and Jesus tells them that He never knew them.
Adding works to mental assent can deceive someone into thinking they are saved when they are not.
Salvation, being born again, changes one from the inside, not the outside. Lot was called *righteous Lot, hardly a title I would confer on him and I doubt many people of ANY religion would consider HIM saved. But God knew.
The Pharisees kept the law perfectly but were white washed tombs.
God prepared works in advance for us to walk in, that is true, but the fruit of the Spirit is not works, but rather Love, joy peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.
Now, tell me. What good works does Catholicism teach we have to do to be saved and how do you know when you've done enough, and how does that pay the penalty of death that our sin demands?
Now why would you say things that contradict scripture?
"Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life." (John 5:24)
Notice that Most assuredly? Those are the words of the Holy Spirit as written by John. Do you doubt what the Holy Spirit said?
Hebrews 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: 12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; 13 From henceforth expecting till his enemies be made his footstool. 14 For by one offering he hath perfected for ever them that are sanctified. Notice that once for all and perfected for ever. Perfected for ever is somehow not perfected forever in your world? Once again, why do you doubt what the Holy Spirit says?
1 Corinthians 6:11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
So we are washed, sanctified, justified, and perfected forever by the Spirit of our God. Did you notice that it didn’t mention that we are any of those things of ourselves or what we do?
Doubting what the Holy Spirit says is rather a serious offense.
