Even without the Book of Sirach (which, I might add, Anglicans read, but we do not use it to form official doctrine), that quote from St. James hits the nail on the head. Although there have been many times in history where God has ‘stepped in’ directly, He also chooses to work through human beings and our good works/‘fruits of the Spirt’.
This reminds me of an old joke:
A Baptist minister living in the lowlands is stuck in a flood in his house. As the floodwaters rise, he climbs to the second floor and finally to the roof, constantly praying that God would save him from certain death. His faith in God taking direct action never wavers.
A rescue boat comes by, but he shouts out to them, “Leave me alone and go help the godless, for God will save me.”
The waters continue to rise and come up to his waist.
A rescue chopper flies over and the minister shouts out, “Go help the godless. God will protect me.”
The waters continue to rise and come up to his neck.
A large piece of driftwood floats by and the Baptist gusses that it could hold his weight, but he cries, “I have too much faith in God to try and save myself. He will protect me.”
Finally, the minister drowns and ascends to Heaven and, at the pearly gates, he sees St. Peter and calls out to him, "St. Peter, why didn’t God save me from drowing? I prayed and prayed. I even turned away mere human rescuers.
St. Peter checks out the Heavenly records, “I see. Didn’t that boat and helicopter reach you? As a last resort, He sent that piece of driftwood…”
I am not trying to make light of a serios and tragic occurrence, but I’m trying to (perhap with a bit of humor) point out a danger found in many parts of Christianity. Certainly, prayer is very important and miraculous events do occur, but God has also chosen to work with and through ourselves and other people for the benefit of His creation.
