This morning I realized that in praying the Chaplet of Divine Mercy, we beg God's mercy by offering him the Body and Blood, Soul and Divinity of of his Dearly Beloved Son in atonement for our sins... Then in St. Gertrude's Prayer for the souls in purgatory, again we start out by offering the Eternal Father the Most Precious Blood of Jesus. Both these prayers were dictated by Jesus, to St. Faustina in the first example. It just clearly shows that we have no merit at all. Mercy comes only through God's mercy. Our only suitable role is to surrender to his Divine Mercy. We must realize that this is a terrific blessing that God cares for us.
