I watched the video twice. Still trying to figure out where he was coming from.
I say salvation comes from Christ through ones confessing and believing. No other way.
Individual choice.
The point Paul was making was its not about a lable based on a mans name.
Its not about following Calvin (which I dont) Its about how does regeneration take place and that its all an act of God. A man that is dead in sin can do nothing to change his estate on his own as he is spiritural dead only God can wake us up to the reality of our sinfull condition and cause us to want to change, A child in a mud puddle will never have an apreication for an ocean as long as he is content in the puddle. He will even fight you kicking and screaming if you try to make him leave it.
Only God can change a sinners heart! Its a miracle everytime a sinner repents and makes Christ Lord of their life. Its a gift of God so no man can boast.
