“Then Peter approaching asked him, ‘Lord, if my brother sins against me, how often must I forgive him? As many as seven times?’ Jesus answered, ‘I say to you, not seven times but seventy-seven times.’” (Matt. 18:21-22) Luke’s gospel also has similar advice: “If your brother sins, rebuke him; and if he repents, forgive him. And if he wrongs you seven times in one day and returns to you seven times saying, 'I am sorry,' you should forgive him." (Luke 17:3-4) Jesus’ teachings are to challenge our limit: “So be perfect, just as your heavenly Father is perfect.” (Matt. 5:48) Is it possible? "What is impossible for human beings is possible for God." (Luke 18:27) St. Paul said: “Since you have taken off the old self with its practices and have put on the new self, which is being renewed, for knowledge, in the image of its creator…..Put on then, as God's chosen ones, holy and beloved, heartfelt compassion, kindness, humility, gentleness, and patience, bearing with one another and forgiving one another, if one has a grievance against another; as the Lord has forgiven you, so must you also do.” ( Col. 3:9-10; 12-13) When Jesus had Passover dinner with his disciples, he washed their feet and also said to them, "Do you realize what I have done for you? You call me 'teacher' and 'master,' and rightly so, for indeed I am. If I, therefore, the master and teacher, have washed your feet, you ought to wash one another's feet. I have given you a model to follow, so that as I have done for you, you should also do.” (John 13:12-15) The point “Seventy times seven” is not about quantity. Jesus did not explicitly explain, he only acted it out. Peter had denied the Lord three times. Before Jesus ascended into heaven, he only asked Peter thrice: “Do you love me?” The real key point is whether we really wish to rely on Jesus, learn to wash others’ feet just like he did.
