Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to everyone’s conscience in the sight of God. 3And even if our gospel is veiled, it is veiled to those who are perishing. 4The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God. 5For what we preach is not ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus’ sake. Paul is saying a few things in this passage. He first is saying that they don't use gimmicks or tricks to convey the message of the gospel. In today's church there is almost no other way that they operate. Everyone from raffles to pastors "flying" in on a zipline. It's nuts! New Spring church began it's Easter service a few years back, by playing, Highway to Hell, an AC DC song. (I can't tell you how sick that makes me) All if this is done in the name of "reaching the lost". Paul will have none of it. He will not even use eloquent speech as a way to attract or proclaim the gospel. The gospel is proclaimed and it is either heard or not. Paul knows that he has no control over that, and he also likely knows that gimmicks can make false coverts. Paul knows that there is no need for gimmicks as the gospel is perfectly clear. A child could understand it! Anyone could easily understand it. What stands in the way is the not the message but the eyes and ears to see and hear it. Who is it that gives sight to the blind and hearing to the deaf?
