If you are a Christian and you believe in God through your FAITH, you face many challenges to that FAITH from a variety of sources such as;
1) Internal personal doubt
2) Attack and temptation from the devil
3) Contact with other religions
4) Contact with non-believers and atheists
So, what do you do to maintain your faith in God? Do you read up on Christian and bible history to shore up your faith? Do you simply pray to god for more faith? Do you bury your head in the sand? Do you avoid contact with non-Christians and atheists.
I would like to how you sustain your faith.
