18But someone will say, "You have faith; I have deeds."Two points stand out to me here. In my typical fashion, let me start at the back of this passage, in verse 19.Show me your faith without deeds, and I will show you my faith by what I do. 19You believe that there is one God. Good! Even the demons believe that — and shudder.
James 2:18-19
Hear, O Israel: The Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your strength.I'm going to guess James was saying, "It's not enough to recite the ‘Shema’ you have to do the acts faith requires."Deuteronomy 6:4-5
