Please note Jesus was speaking to a group of Jews. After hearing Jesus's words, Jews had to abandon the group practicing Judaism and
follow Christ as individuals. (
Gal 3:10-14) Imagine how it would even more apply to a little Muslim boy or girl, or man or woman, growing from infancy being taught the
Islamic faith
[to kill non-Muslims]. How, though, about a
Catholic or Mormon or other
Protestant, taught "their" beliefs from youth? This correction by Jesus to set themselves free of their previous form of worship applies to every person in every religion; but not to "individuals" actually and personally
following Jesus's teachings. If you feel
blessed by being a member of any of those sects given special names by men, if you call yourself anything besides or in addition to "Christian," (
Acts 11:26) I fear you do not know Christ at all... It is not named
groups of people God is preserving alive. It is individuals with
absolute faith in the words of Christ. (
Mal 3:16-4:3;
Heb 10:38-39)
