Ps 102:13

“"Yea, like as a father pities his own children, even so has the Lord had mercy on them that fear Him" [Psalm 103:13]. Let Him be as angry as He shall will, He is our Father. But He has scourged us, and afflicted us, and bruised us: He is our Father. Son, if you bewail, wail beneath your Father; do not so with indignation, do not so with the puffing up of pride. What you suffer, whence you mourn, it is medicine, not punishment; it is your chastening, not your condemnation. Do not refuse the scourge, if you dost not wish to be refused your heritage: do not think of what punishment you suffer in the scourge, but what place you have in the Testament.”

“Although God possesses all the most noble properties, He is nevertheless most excellent in this property, namely that of piety. He is pious and merciful, because He spares and protects. The Lord says: "As a father has mercy on his children, so have I had mercy on you." Search all the works of God from the beginning to the end, and you will always find operations of mercy that are great, greater, and greatest. The great operations of divine mercy are the operations of nature; the greater operations of divine mercy are the operations of grace; but the greatest operations are the operations of glory.”
