Doubt did not prevent Jesus from raising Lazarus or Himself from the dead. It did, however, rob Thomas of joy and fellowship with Christ during parts of these events.
The modern Christian church requires no penitence for fellowship. You can bring your sin right along with you! This idea is obviously foreign to scripture.
Having every detail about Who Jesus is and exactly how He saved His people is very important in order to honor Him properly here on earth. But while a man’s confession may be flawed, his salvation is still secure in the finished work of Christ!
Jesus tells James that he would follow Him through sufferings. As recorded in Acts 12, James became the first martyr among the Apostles. He wanted to be where Jesus was and his desire was fulfilled.
