“In whatever he does, he prospers.” (Psalm 1:3)
“He does” denotes an active faith over a conceptual one. “Prove yourselves doers of the Word, and not merely hearers who delude themselves.” (James 1:20) The “effectual doer” is “blessed in what he does.” (James 1:25)
Know the Word, do the Word, and be blessed by and through the Word.
