David Platt on Global Missions

I just finished watching a sermon that David Platt gave at the Together For the Gospel conference recently. He really challenged me to consider the absolute sovereignty of God as the basis for global missions to unreached people groups.  God's sovereignty should give us confidence that His purpose will be accomplished to purchase people from every tribe tongue people and nation.  It gives a new power and significance to the phrase that begins so many prayers and blessings: "Blessed are you LORD our God, King/Sovereign of the Universe..."  As David says,

Our God is in the heavens;
he does all that he pleases. (Psalm 115:3)

Hopefully this sermon will be encouraging to many people.  This site has links to the audio and notes too.
