Your question reflects an over-spiritualization common in Christendom today.
@quietthinker, contemptuously sees anything else as carnal thinking. Christendom has largely abandoned soulful considerations, the needs of the body.
Jesus did not sing kum-ba-ya and tell everyone to consider all their afflictions joy. He tended to the soulful needs of the people, healing them, feeding them, etc. He did not say to be passive and wait for God to act. He commanded us to act - to pray, to seek, to knock, to ask and to spread the word to every people, and even to sell your coat for a sword (not for decorative use). To answer your question, read the verse again.
Proverbs 23:13-14
13 Do not withhold discipline from a child;
if you strike him with a rod, he will not die.
14 If you strike him with the rod,
you will save his soul from Sheol.
It is not referring to what God will do but what you (the parent) are required to do. The Bible is not a theoretical book on the merits of sitting back passively waiting to be acted on but a practical How To Live guide, meaning what action we are to take to live properly. Come on now!
