If the mechanic deviates from any of the manufacturers instructions and causes an accident, he is held accountable. The same goes for how a pilot flies the aircraft. We in the aviation industry have to follow the book, not just for liability purposes, but to do the job right the first time. We, as aviation professionals, need to be people of the "book." 
    Some years ago I was working with a lead man on an engine inspection. I got down to get the right washer for an engine control. The right washer in the right place and the controls won't come apart. The lead man said I didn't need one but I went and got it and put it on anyway, knowing it needed it. Some time later I was to get a review and a pay raise but I didn't get it. They cited this occasion to deny me the raise. Not long after that, after discussing it several times with them, I brought in my basic mechanics handbook and showed them the requirement for that type of washer. I still had a hard time until the chief inspector got into the discussion. It only took a minute for him to look at the situation and declare, "Art's right." Within a week I got my pay raise. The lead man and apparently some of the others didn't know the book. Aircraft mechanics need to be people of the book.
    As practicing Christians, we need to be people of the book. God has made us and knows how we work. He has an intimate concern for us from before birth. Jeremiah tells us of what God told him in;  Jer. 1:5. "Before I formed you in the womb I knew you, and before you were born I consecrated you; I have appointed you a prophet to the nations." God knows us the same way and wants all to come to Him through the truth of His Word. Those of us who have believed His word and obeyed He has given us the name of His beloved Son, Jesus Christ. Because of Him we wear the name Christian. He loves us far more than any aircraft manufacturer loves his airplane. That is why He sent His Son to die for us. He supports us after we are born and even more after we are born again. John 3:3-5. When we are born again He sends His Spirit to help us. Acts 2:38.
    God has given us guidelines for maintaining life in Him. In the beginning the guidelines were verbal and very simple. As people progressed and multiplied on the earth, He gave us more guidelines for our instruction. The written word has come to us as His final instruction and authority for life. This Bible is the maintenance manual for the body and soul and a flight plan for life. It tells us all we need to know, even the basics. If we read it and follow it we will be able to correctly maintain our lives as he intended.
    Just as the aircraft mechanic and the pilot are held accountable for their deviation from the manufacturers instructions, we as Christians will be accountable to the Maker for errors resulting from the deviation from His plan. That is why we as Christians always need to refer to our Maker's instructions. The outcome for those who make that commitment will be rewarding, like Josiah.
    The pilot and mechanic are trained in the basics to do their job then keep on training and gaining more skill on the particular aircraft they are concerned with. They continue to refer to their books to keep current and learn more. The Christian, likewise, must learn the basics then keep on learning, referring to the Book often. Trying to do all aircraft maintenance and flying year after year after only reading the manual once will likely end in the disaster of a crash. Likewise if a Christian only reads the Bible once and does not refer to it again his life will come crashing down in disaster. That means
