You forgot the warning from Mathew that the standards by which you judge others will be the standard by which you will be judged.
I notice that there are loads of Christians who should really be concerned with that particular verse.
Hi Mesthemia, those verses are applied to the population of the world. The "all Nations". It is seen in John 3:16 as well. It is the "whosoever believeth" that has feed the ones who have "hungered and thirsted for righteousness" and "visited those who are in the prision house of Sin and those who are "sick" unto death with the "guilt of Sin". . these have used their "talents" to do so. They have been a "witness unto all the world".
It is those who have thwarted GOD and HIS Message of Salvation at every turn which are denounced.----"Ye did it NOT". "By their fruit ye shall know them."
No place is there an admonition to Love or follow any who are disobedient to the Will and rules set down by GOD. That doesn't mean that any person cannot change from being contrary to the ways of GOD to being "followers". GOD is "long-suffering" " awaiting one to come to Repentence". For one to "Perish" isn't HIS Choice nor is it HIS desired aim in HIS MERCY, LOVE, AND GRACE.
Disobedience and arrogance are the choices one makes and is the "fruit" which is rejected as being "fit for the Heavenly kingdom". Therefore, the "separation"---which was started by that "serpent/Satan" in the Garden of Eden. Believe GOD or Believe the "father of lies".
