The established religious leaders of the first century had the temple, the inspired scriptures, and were faithful to the traditions of their fathers but did not recognize Jesus as Christ. What were they lacking? Faith in God.
John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. 5:40 And ye will not come to me, that ye might have life.
Faith is drawn by grace and directed by the knowledge of Christ. Trust not in the traditions of your fathers but join your faith to Christ in grace and truth and your faith shall be sustained by Him daily and fail not.
