I am not the one who said that God always does ‘the best possible thing.’
Nor would many humans say that what God does is, by human standards, the best possible thing. For instance, I cannot account for the many absolutely horrible parasites and diseases that exist in the world that cause so much suffering on people. But I DO see intelligence in the design of the universe the DNA codes, and the events of history.
I don’t know why so many innocent people suffer from natural disasters. But God has put me exactly in the right time and place and nudged me to do certain things that were exactly what was needed at the time that has affirmed God’s existence.
Once, when someone I was trying to help through an illness was suffering immensely and I couldn’t pray for her because I believed it would not work, I needed proof of God’s existence, God nudged me to buy two record albums at a random yard sale I passed on my way to work. Then, I sensed that God was nudging me to give them to a drama teacher in an afterschool activities program where I worked. I felt silly and apologetic but did this.
The drama teacher had also been praying for a sign from God, and those two record albums had belonged to him eight years prior and had disappeared from a school office where he had stored them temporarily, One of them had his wife’s first and maiden name on it.
Why God can arrange that but does not alleviate the suffering of the person I was caring for, I have no idea. God’s standard is not mine. But the woman who was ill that I couldn’t pray for—she had faith and I didn’t. And she is in a better place now. She would say, God chose to heal her in heaven. Those would have been her words after a life of suffering.
