Why did Jesus say we should forgive seventy times seven?

When Peter asked how many times he should forgive, suggesting seven times, Jesus responded with 'seventy times seven' (Matthew 18:22). This response signifies that our forgiveness should never run out, highlighting that true Christian forgiveness is generous and unlimited. It emphasizes the understanding that, as recipients of God's infinite mercy, we must display that same mercy toward others, regardless of the frequency or severity of their offenses against us. This radical forgiveness is an essential characteristic of the kingdom of heaven.
