It is still up to us as Christians to make decisions based on the Word - obedience is what God desires. He prompts us with Scripture when needed. This reminds me of a little boy whose mother told him to bring the broom in from the back porch late one night. HE was scared of the dark - so she told him - “don’t worry - God will help you.” So, the little boy stuck his hand out the back door and said - “God, hand me the broom.” We still have to put legs to our faith.
Suppose you have an unconverted person, but who is positive towards Christianity and is otherwise very good for the economy, etc etc., and he is running against: A Born-Again Believer or, if you're Catholic, a guy so holy he performs miracles with his touch, but who supports amnesty, (un)Free trade and many other things you know will destroy the country?
