I have no problem with people propagating whatever in whichever way they wish.
BUT
If you are going to call what you are doing preaching THE Gospel or Teaching and Instructing in righteousness with the bible as the basis then you have to conform to scripture.
Why don't people just go ahead and start a 'positive thinking your best life now' religion like Oprah, they can call it MAVUNINSANITY or whatever and have akina Oprah, Joel Osteen , Deepak Chopra and others of this genres content as their scriptures... they can then hypnotize and high five themselves in their seminars and conferences till they are blue in the face.... they can compete with akina tahiti and apple bees in their posters to capture their target audience and stay 'relevant'.
Why drag the bible and Jesus the Christ into all this?
A teen in 2014 looking for truth is under no illusions about sex physically but is probably lost with regard to sex in its proper context.
So you fill a Church with teens drawn by a sexually suggestive poster to then lead them to the way of truth?
How?
The very nature of the Gospel goes contrary to the flesh in every way.. how then can you use devices of the flesh to lead anyone to the truth of the Gospel?
There is no precedent to this in all of scripture nor is it there in church history.
Consider this text,
2nd Peter 2
Peter talking about false teachers
Quote:17 These people are springs without water and mists driven by a storm. Blackest darkness is reserved for them. 18 For they mouth empty, boastful words and, by appealing to the lustful desires of the flesh, they entice people who are just escaping from those who live in error. 19 They promise them freedom, while they themselves are slaves of depravity—for “people are slaves to whatever has mastered them.” 20 If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. 21 It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them.
