The man is Joel Osteen. Opinions vary but I believe we can learn some things here.
First is, people obviously respond to encouragement especially when they believe those exhortations fit their lives.
Secondly, dressing neatly in a suit and tie does not seem to hurt the crowd size; again, if they believe the message fits them.
Of course, we know making the truth fit them is more important eternally than what the audience might think fits them! See God’s Word on this in II Tim. 4:1-5.
Third and foremost and quite sadly, Mr. Osteen preaches almost entirely assuming that His listeners (live and via media) are true believers. This is a SAD AND SHOCKING error but it is all too common in churches today.
Here are two observations and a challenge.
The more a church does to make it services attractive to the unchurched the more the preacher should assume that many lost people are present. Be wise!
Also, Jesus had 12 close disciples and one never was saved; Judas Iscariot. Beware!
Sometimes the harvest is right before your face. We CANNOT disciple “goats”. NEVER assume that because people like you and your preaching that they are redeemed. Liking you may be part of what Christ is doing so that they can see their sin, see Him and “be born again”. Preacher, be vigilant!
