Paul Tautges said this quote
“ If we regularly ponder the depth of our own sinfulness, like the woman who washed Jesus' feet with her tears, and consider the greater depth of God's forgiveness, we will grow in our love for him. It is when we forget God's benefits that our hearts become proud. If we are not careful, we who have been forgiven much can act like those who think they have been forgiven little and, consequently, become slow to forgive others who sin against us. ”
