Yesterday I listened to a sermon by Andy Stanley about discerning God's will. My biggest takeaway was that if you want to know God's will, don't seek to hear some audible voice giving you direction. Instead, seek to know GOD better. Learn what is important to God. Notice what He is doing in the world around you. Seek His face.
Deuteronomy 6:5 You shall love the Lord your God with all your heart and with all your soul and with all your might. (NASB)
