Matthew 18:22

Jesus saith unto him, I say not unto thee, Until seven times; but, Until seventy times seven.

Christ did not mean that Christians should keep a ledger, exactly calculating a precise number such as 490, or using a variant reading, 70 times and 7. This simply means that a Christian must have the spiritual resources to keep on forgiving. Forgiveness of others was made a constant pre-condition of man's forgiveness by the Father, not only in these words of Jesus here, but upon other occasions as well. The business of forgiveness is so important that Christ immediately introduced one of his longest parables in order to reinforce the teaching and repeat the absolute necessity of forgiveness at the conclusion of it.
