Philippians 1:9-11
And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless until the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ - to the glory and praise of God.

How do we hear the voice of God?
We need to know that FIRST to hear Gods voice we must know him. We should always be striving to learn his character and build an intimate relationship with Him. This is all accomplished through His word.
"trying to hear Gods voice without knowing his word is irresponsible."
