My 7yo asked me why I pray if God doesn't always answer

Guys this one hit me hard. We were doing bedtime prayers and my son just looks at me and asks why we pray if God doesn't always say yes. I froze for a minute because honestly it's a great question. Ended up telling him that prayer is more about talking to God and trusting Him even when we don't get what we want, kind of like how he trusts me to make good decisions for him. He seemed to get it but man it made me realize I need to be more intentional about showing my kids what faith actually looks like in real life, not just at church on Sunday.
