Whenever you face trials of any kind, consider it nothing but joy, because you know that the testing of your faith produces endurance; and let endurance have its full effect. (James 1:2-6)
Jesus told his disciples a parable, “Can a blind person guide a blind person? Will not both fall into a pit? No disciple is superior to the teacher; but when fully trained, every disciple will be like his teacher.” Luke 6:39–40
