“Jesus said to him.
‘If you are able!
Can be done
For the one
ὁ δὲ Ἰησοῦς εἶπεν αὐτῷ Τὸ Εἰ δύνῃ, πάντα δυνατὰ τῷ πιστεύοντι.
This is unique to Mark. Jesus said to him (ὁ δὲ Ἰησοῦς εἶπεν αὐτῷ). If you are able (Τὸ Εἰ δύνῃ), all things can be done (πάντα δυνατὰ) for the one who believes (τῷ πιστεύοντι). Jesus responded that belief was the key ingredient for any success in this area.
