Would you mind elaborating? I personally enjoy the music Hillsong puts out, but am always curious about the inner workings of an organization such as theirs.
In the case of IHOP they have sexualized lyrics which they front as worship music by over emphasizing being the Bride of Christ. This leads sexually frustrated / confused (in a Christian viewpoint / sense) youths even more confused about Jesus and their relationship with Him. Its a lot to take all at once so research it and pray about it and take your time. I just personally avoid IHOP / Hillsong for multiple reasons. The other thing to remember is they are not all at fault some are just there genuinely or misled into being there.
