For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body. James the Apostle taught this in his catholic epistle, 3:2.
To teach is a very dangerous proposition that opens me, the author, to all kinds of danger of judgment. To judge is to accept responsibility for incorrect judgment, which is itself judgment. It behooves me to be as precise as possible. I must relay truth, first and foremost. This requires me to understand God and then explain what I understand. He should guide every step and be central to it.
Jesus commands no less. Matthew writes in his gospel, 5:48. Be ye therefore perfect, even as your Father which is in heaven is perfect. Naturally, I fall short of such a high standard, but Jesus also teaches something heartening just previous to this, verse 19. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
It is my prayer that the words I write here will grant me this title: great in the kingdom of heaven. It is my prayer that the words I write here will never teach to break the commandments of Jesus.
Paul in Ephesians 4:29: Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Peter teaches likewise in his first epistle, 3:10,11. For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile: Let him eschew evil, and do good; let him seek peace, and ensue it.
It is very dangerous to admit words into one's mind. Language has a property of hypnosis to it. Exposure to ideas is incredibly dangerous. Words and ideas have the potential to change your life. You should not do this carelessly! Matter of fact, I'd recommend against following the teachings of anyone who does not explicitly warn you about the danger of following teachings in the abstract. Jesus cautions about this according to the gospel of Matthew, 24:24. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Ecclesiastes 1:18 makes this nature very plain. For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow. I can testify to the truth of this.
I teach exclusively from the King James Bible. While it has its faults, it is close enough to correct for almost all exegesis. There's an article to be written about the interface between the English language and its Biblical roots. The only texts that have more potential to be authoritative are written in Hebrew and Greek, and these are not particularly useful for English-language hermeneutics. There's a concept in my head that I term "semantic equivalency" using which the King James edition in particular excels.
In most cases, when doing serious work, I go back to the original languages to validate the truth of what I'm teaching.
In Bible-proven work, Scipture passages are always denoted with bold font, with the words of Jesus in red. This page demonstrates this convention.
