Missions has been and still is a consuming desire on my heart. When the Lord will release us to serve is up to him (notice I said “when”. I firmly believe it is “when”, not “if”). The link below contains a sermon by Michael Oh which he gave at Desiring God’s 2009 conference. This must be one of the best sermons I’ve heard on missions. I have listened to this sermon more than once and have benefited from it each time. I hope other listeners benefit as well.
