Yes u are right.The love is oposite for fear.Simply said-all negative feelings are devil's attacks-we said"sad by spirit" aka depressed.-that enter in u.It's energy....sucks u like a vampire.Some people can't get so much and attempt suicide...jealosy,envy,malice,hate,greedness.....all these are like livin' creatures from the world bellow,which tormented us....and if we got faith(always not enough),and most important-the protection of Heaven wr are goin' through...must keep&feed the angels-love,compassion,hope,patience,inner balance,simple life....that's how i feel the world....same is valid and for some muslim probably,cause may be all religions are fundamentaly the same....there is always a Higher power.Everything is happened for a reason.U got the beginning&u got the End.May be "Kingdome of God",that Christ talk about is just some kind of nirvana?breaking the circle of Samsara....'cause many scholars said,that early Christian recognize reincarnation of the soul.Idk.I even know less day by day.About God&human and what's happened with the world&people.Seems to me,that all are loose their minds
