The first thing enemies do upon commencing hositilities is to exchange vices. Let's hope our secular nation does not devolve into a theocracy ruled by self-righteous Bible Thumpers who will be every bit as authoritarian as the Taliban given half the chance.
People who imagine they can talk to God are delusional. But people who claim that God talks back to them are either insane and dangerous or crafty con artists and dangerous. People in power who imagine that they have a book of instructions written by God tend to be intolerant of those who don't follow the instructions to the letter.
The separation of Church and State should be maintained absolutely. Otherwise the dominant religious group will monopolize the state institutions, come to think of itself as the owner of those institutions and eventually impose its collective will with the same methods the Taliban used. If kids want to pray publicly in groups they are completely free to go to the Church of their choice on their own time.
