Can fervent prayers beside the graveyard of my late father remove the wickedness I inherited entirely from me?

It is your nature, accept it.

War is peace; you'll never be at peace until you accept your nature and tell them all to go to hell.

Why pray beside the grave of your father? You can pray at home or at work just as well. Why are you accused of being wicked? What have you done that would cause them to label you in that manner?

GOD can and will remove any wickedness if you truly want to get rid of it. You have to give it to him long enough for him to fix it.

As far as what other people think, that is their business. You can only take care of you.

No, but you can break off generational curses. Talk to a pentecostal church about it.

...No... Jesus clearly said "let the dead bury the dead". You can, however... you have the authority to boldly approach the Throne of Grace and ask God.... It's your turn to "go for it".

'your' people will probably just think you're nuts if you do that.
