Hello ,
"When we hate our enemies we give them power over us - power over our sleep, our appetites, our happiness... Our hate is not hurting them, but it is turning our days & our nights into hellish turmoil."
Dale Carnegie
The bible says to love our enemies, and to pray for them that use us in less than desirable ways. We don't just wake up one morning and decide to have a change of heart that would cause us to do that. It's God's department, and we can only have that change of heart if He brings it to our lives.
Have a great day and God bless!
