To balance forgiveness with correction is to ensure power in words.

Contemplation:

To only correct without having any good wishes is to waste words.  It
will further distance the gap and create a barrier forever.  On the
other hand, just forgiveness will not ensure growth in the other
person, and he will only keep repeating his mistakes.  A balance of
both is what brings power in our words, which will ensure his positive
growth.

Application:

When I find someone making a mistake, I need to make sure that I
provide the  right environment for his change before correcting him. 
To provide the right environment means to have an attitude of
forgiveness and good wishes.
This will automatically bring positivity in my words through which he
can find some means of benefit for himself.
