I have a question for the Christian ladies on this app.

🎀S
What is the point of typing out a prayer and posting it on a social media platform? I literally don't understand the point. Prayers are for God to hear and he doesn't have a social media account as far as I know. 
Not judging or bashing I would just like a little insight 
(If you're not a Christian you needn't reply. This isn't a debate about how real or fake God or religion is, we get it you aren't a person of faith.)
