Seems a little far fetched, doesn't it? How could anyone come to the conclusion to do this to a teacher? Yet, far worse has been done in the name of God, so misinterpreting the Bible is no surprise. Remember the crusades, or how about the inquisition? When it comes to correctly understanding the message of the Bible, a heart unadulterated by the world is a necessity. Consider this passage from the book of Titus...
Titus 1:15-16 (WEB)
15) To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure; but both their mind and their conscience are defiled.
16) They profess that they know God, but by their works they deny him, being abominable, disobedient, and unfit for any good work.
To me, these verses explain how so much evil can be done in the name of God. Sin corrupts the mind as well as the body and leads to error upon error. As far as the picture goes, I am reminded of the first line of the Christian hymn: Nearer my God to thee "...even though it be a cross...". There are worst things than dying for Jesus... review verses 15 and 16 to see what I mean.
