If God is not a cosmic Candyman who gives us everything that we want then why did Jesus tell us to pray for anything in his name?

So I was listening to one of the live Q and As conducted by Dr Frank Turek on his official YouTube channel ***Cross Examined Org***, someone asked him if the Word of Faith movement are right, in the sense that God wants everyone to be healthy and wealthy, The doctor responded with a sense of humor and I quote >***God is not a cosmic candyman who gives us everything that we want, earthly fathers don't give kids everything they want, if they do, what happens to the kid? The kid becomes spoilt, God does not give us everything we want for our own good*** The thing is Jesus himself removed the veil on our prayer requests by using the term ***anything***, any request we make to the Father in his name shall be given to us. *John 14:13* >You may ask me for anything in my name, and I will do it Paul also said that the believer can do all things through Jesus Christ who strengthens them. *Phillipians 4:13* >I can do all things through Christ which strengtheneth me. All things means literally all things and anything means anything literally, so why is Doctor Turek right that God is not a cosmic candyman who gives believers what they want?
