I am sure they are saying that it is God’s will they expand as a spin for what is really happening, but what is its actual purpose?
Actually, one of the GB, Guy Pierce, publicly admitted at the 127th annual meeting of the Watch Tower Society, held on October 1st, 2011, that they did NOT know if it is/was Jehovah's will or not to do this.
“There are plans to develop a 248-acre (100 ha) property at Warwick. ‘Although we are not yet certain of Jehovah’s will regarding Warwick,’ said Brother Pierce, ‘we are proceeding to develop the site with the intention of relocating the world headquarters of Jehovah’s Witnesses there.’ Plans are also being made to use a 50-acre (20 ha) parcel of land situated six miles (10 km) north of Warwick to facilitate the staging of machinery and building material. ‘Once construction is permitted, we hope to complete the entire project within four years,’ said Brother Pierce. ‘Then our property in Brooklyn can be sold.'” - w12 8/15 p. 17
Well I guess we now know the answer. Stephen Lett informed us last month that there's a "shortfall" of funds for the project. So evidently it must not have been Jehovah's will.
