Is everyone able to forgive?

You are forgive but you can never truly forget.

No. I can never forgive anyone. Well, it depends upon the person who commits a mistake and what is that level.

No, I am not. Oh, I can act like I forgive; but only 'in order to allow the wrongdoer to "repay".' I think it was Kris Kristofferson (playing a character who was rending vengeance upon 'an evildoer' ... or some other tortured character) who said, "God forgives," rapped on a robotic limb he had to wear, "I don't!" We can't even forgive ourselves! It's like 'getting sick & getting well'---we don't get "repayment" for the time we were sick; the most we can do is rest, get well, and maybe avoid doing 'what made us sick' in order to stay well. That's where Christians like to blur 'forgiveness' and 'grace' together, but they're not the same thing. (That's why--even though it's said that Lord Jesus Christ "paid the price" so that we don't have to die--every Christian that ever lived is still going to die!) The 'forgiveness'---I'm not even sure how that works (something like 'we believe we're paid-for, so future children-of-God will bring us back?') The 'grace' is simply "not holding a grudge." Bringing-up a real example would be 'remembering that I'm still holding on to a grudge.' So ... well, this is a real example too; but I'm not the one 'sinned-against'---take one of President Donald Trump's many 'offensive remarks.' Because of these, The Press frequently accuses him and interrupts him (and his staff) before they can explain.

I sometimes find it very difficult to forgive someone.

Not always. I cannot forgive the lady that lives below us for not letting me get my cat that was out all night and she was inside warm and snug and I had to end up calling the polce for help.

I am. I forgive and forget very easily, but i feel it's a weakness !!

I was never a forgiving person. I usually hold grudges for many years. And then some. But I do think of myself as a fair person, one who will listen to reason and understand another persons point of view. But don't cross me. That is not how I play.

Jesus taught us to forgive, He said, forgive us our sins as we forgive others. So the equation is very simple, you don't forgive, then God will not forgive you.

Indeed forgiveness is difficult. I think most people can't do it. Maybe you should try the ''forgive but don't forget ''. It actually works ;) For me it does.
