The Bible is well able, and does in fact, interpret itself, because it is a masterful work of divine literature, from God's mouth dictated to holy men. Not only that, but the Holy Spirit of our Lord Jesus Christ will also help you understand what you are reading, maybe not right away, but he will get the answer to you, I promise, he has done that very thing for me many times over. You must also LIVE in holiness unto the Lord Jesus Christ, without hypocrisy. Well, there you have it, the basic Christian beliefs. Know them. Breath them. Live them, and spread the good news while there is still time -Amen!
