My output reveals my input. If my heart is void of the Word of God, then my words (“talk of the lips”-Prov. 14:23) yield no fruit. If I stay plugged in the Word, the Holy Spirit keeps my heart renewed with a desire to serve (“in all labour there is profit”-Prov. 14:23).
As I stay in tuned with what God says through His Word, then if He gives me a message to share, fine; if not, I know my obedience will prove fruitful–hence the well known saying, ‘actions speak louder than words.’
