I got this from somewhere. I don't know whether it's common expression or if someone deserves credit for it. I expect they won't mind; this is just a blog, after all.
It's a summary of the Divine Mercy as understood by the great and humble St. Faustina. It's easy to commit to memory, as easy as "ABC":
A — Ask for His Mercy. God wants us to approach
Him in prayer constantly, repenting of our sins and
asking Him to pour His mercy out upon us and upon
the whole world.
B — Be merciful. God wants us to receive His mercy
and let it flow through us to others. He wants us to
extend love and forgiveness to others just as He does
C — Completely trust in Jesus. God wants us to know
that the graces of His mercy are dependent upon our
trust. The more we trust in Jesus, the more we will
There is little that I need to add to this. Let's beg God to make us this way. Ask mercy, Be merciful, Completely trust...A, B, C. God loves us so much. We are afraid of suffering, because we don't understand that He is trying to open us up and enlarge us according to the measure of His love. We must trust. If we feel like we can't trust Him, then we must ask Him to enable us to trust Him. To ask Him for this is to begin, already, to trust. And the more we trust in Jesus, the more we will receive.
