Am I therefore become your enemy, because I tell you the truth? They zealously affect you, but not well; yea, they would exclude you, that ye might affect them. But it is good to be zealously affected always in a good thing, and not only when I am present with you.
True friends love you which means they love you enough to tell you the truth even though it may be something you really don't want to hear. It doesn't make them your enemy, but it shows their true love for you. ("Iron sharpeneth iron; so a man sharpeneth the countenance of his friend." ~ Proverbs 27:17)
There will be people in life who try to turn you from your beliefs and convince you that they are right, but if what you believe is true, you should stick with truth.
God's Word is true! There are definitely people who try to twist or change it to fit their desires. Stand firm on Truth!
