Assuming a belief in God and forgiveness (which I do not share), it is entirely within the teachings of Christianity for God to forgive your wrongdoings--but your wife, neighbor, boss, or whoever else you wronged does not have to forgive you. God's forgiveness gives *you* peace, but the people you harmed don't necessarily have that peace.
