Note 7 at Mt 18:22: Peter thought he was being very generous by offering to forgive his brother 7 times in one day, but Jesus said he should forgive him 490 times in one day. It would be impossible to have someone sin against us 490 times in one day. Jesus was actually saying that there should be no limit to our forgiveness.

In context, this principle applies to church discipline (see note 5 at Mt 18:17 and note 6 at Mt 18:18). Regardless of how many times we have to discipline our brothers or sisters, if they repent each time (Lu 17:4), we are supposed to forgive them and confirm our love unto them (2Co 2:6-8).

If God expects us to forgive a brother who has trespassed against us 490 times in one day (actually an unlimited number of times), certainly He who is love (1Jo 4:8) will do no less with us.
