Calvin writes of the falseness of these accusations and our temptation to believe such words in our own adversities:
"It is contrary to the nature of faith that the word now should be insisted on by those whom God is training by the cross and by adversity to obedience, and whom he entreats to pray and to call on his name, for these are rather the testimonies of his fatherly love, as the apostle tells us (Heb. 12:6). But consider this peculiarity, that though Christ was the 'well-beloved Son' (Matt. 3:17; 17:5), yet he was not delivered from death until he had endured the punishment which we deserved, for that was the price by which our salvation was purchased."
May I never demand, as proof of God's love, the removal of the very thing His love has laid upon me.
"'For the Lord disciplines the one he loves, and chastises every son whom he receives.'
It is for discipline that you have to endure. God is treating you as sons."
~ Hebrews 12:6-7a, ESV
