Jesus says quite a few times that if you have enough faith you can do anything.

Matthew 21:21

Jesus replied, "Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, 'Go, throw yourself into the sea,' and it will be done.

Luke 17:6

He replied, "If you have faith as small as a mustard seed, you can say to this mulberry tree, 'Be uprooted and planted in the sea,' and it will obey you.

He's talking to his apostles, but who is Jesus addressing when he says "you"?

Does Jesus suggest that we can do those miracles today,
was that something his apostles could do back in the times of Christ,
or is this a parable of the forgiveness of sins?
