Question for Evangelical Christians?

Of course you can know the mind of God. That is why He took the time to have His words written down. We can KNOW what He wants and how to please Him. Read the Gospels, do what they did in Acts and then use the epistles to hone your life. That way you know. The word, the Bible is the standard by which we will be judged. A loving Ruler makes sure that He has a law so that all His subjects know what is right and what is wrong.
