As there is neither objective evidence that a Christian God exists nor objective evidence that a Christian God does not exist, this is an impossible question. If you are a believer you will try your best to convince yourself and others of the existence. If you are a non believer you may try and convince believers they are misguided, or at the worst, as written on this site not so long ago, they are mentally ill (disgraceful) , Neither party can prove their case, therefore its one of life's eternal mysteries.
