I will give you the fact that you posted some Scriptures which "YOU" believe validate what you have been told. I do not agree with your understanding of their meaning.Easy.
I showed you WITH SCRIPTURE that we work for GOD,,,,
and not as evidence toward man...
and definitely not as evidence toward God..since God does not require "evidence".
You had stated that we do good works as "evidence".
No. We do good works because we are obeying Jesus' commandments.
Then I showed you WITH SCRIPTURE that we will be judged by our good works.
Then you asked a couple of silly questions:
1. If a person dies on their death bed and seek salvation..will they be saved?
2. Was the thief on the cross saved because he couldn't do a good work?
You could just reply to the EVIDENCE part and forget about the silly questions part.
I believe that we do good works after we are saved out of the Love we have for what God did for us. IF...IF you believe that to be an act of obedience....OK with me as I do not see either side as being a essential to salvation.
