What discerning criteria is used between real prophets and false prophets?
You make a grand, sweeping accusation against South Korean and it's Christians, on what factual basis? Have you been over there? Do you personally know all of the things they have tried to do to help the North? I noticed you have not responded to questions such as these in this thread. Who are you to judge them, and on what basis?
P.S. Have you invited 10 inner city ghetto families from the city closest to you (your neighbors) to live in tents on your property, rent free? NO?! Now you're in judgment and will have doom come upon you... /sarcasm
I haven't observed any Korean believers, from either North or South, fail to exhibit love for their fellow man or their fellow believers in Christ.
I have observed a split body of people, generally of one race and tongue, also known as a nation, with many unbelievers with very real animosities towards anything Christian.
National governance is a divine institution for believers and unbelievers alike. When the legitimate authority of national governance is violated, the divine blessings available to that institution are infringed.
If unbelievers from North Korea attempt to invade the South Korean nation and remove the freedoms of believers to study Scripture and witness the Gospel, such actions are nowhere defended in Scripture.
More primal than love for one's fellow man, is for each and every believer to remain in fellowship with God through faith in Christ by His protocol. Loving one's fellow man as oneself includes the use of force to defend legitimate authority and living within the domain of legitimate authority and respecting those authorities.
The existence of conflict doesn't entail love doesn't exist. On the contrary, a true perseverant love will always result in separation between good and evil, especially when divinely judged.
Forgiveness without repentence merely implies the degeneration of good to accept the force of evil.
