My brothers and sisters ,i want you to all know that the enermy has already be destroyed right from time,the only enermy of man is the satan and the lord has given ur power over him,we are a royal priesthood,a peculiar nation and a choosing race who share a joint heir with christ,so the enermy is already defeated,stop seeing your friends,family,school mates as your enermy,the book of psalms say anyone who decided to be your enermy has already falling,so let them live long to see what you will be in future.

True.

Bitterness makes the situation hard. When you can smile (genuinely) through animosity, even the devil will make peace with you.

Nb: not a believer of praying FOR enemies though.

Satan and his children are our real enemies . Any friend, brother or sister , mother ,father etc who hates you and fighting you spiritually using witchcrafts ,charms , spell etc is your enemy and must pray against them , if not , they will destroy you and your salvation.

For examples :

Acts 13:8-11 KJV
But Elymas the sorcerer (for so is his name by interpretation) withstood them, seeking to turn away the deputy from the faith. [9] Then Saul, (who also is called Paul,) filled with the Holy Ghost, set his eyes on him, [10] And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord? [11] And now, behold, the hand of the Lord is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell on him a mist and a darkness; and he went about seeking some to lead him by the hand.
