Hi Magee, Jesus is speaking truth to his disciples in the Sermon on the Mount. He is using "hyperbole" an exaggeration of truth to make his point sure and believable.
Example: In Chapter 5:29 on adultry, he says, "if" your eye offends you "pluck it out", do people think Jesus wants us to pluck out our eye if we lust for another woman, of course not, Jesus is using hyperbole an exaggeration to get his point across and He does this all through "The Sermon on the Mount."
Point: It is the same identical idea "hyperbole" that Jesus uses in Matthew 6:14,15 about forgiveness. Have you ever held unforgiveness in your heart for someone, that is his point don't do it or God will not forgive you. Will God forgive you? Yes He will, but Jesus speaks in hyperbole an exaggeration to get his point across to His disciples, it is imperative to forgive, even your enemies.
Bottom line; know what type of language a person is using before you make an improper "Interpretation."
A false interpretation will always, always lead to a false "application" and that directly effects everyone.
God bless!
