Forgiveness-Can we give it?

I was thinking this morning about the concept of forgiveness. God has provided ultimate forgiveness for those who have accepted Christs sacrifice. Can we who say that we are his representatives here on earth, can we forgive others the same way? Can we forgive an offense 7 x 70 as Jesus said? How do you feel about being both forgiven and providing the same measure of grace to the one who has offended you?
