That the "Pioneer Spirit" is actually a very real spirit propounded as something good and necessary for decades among all JW's, and that this said "Spirit" is actually employed by certain individuals for the sake of recruiting pioneers through trickery and compulsion which is not Christian at all in origin. See 2 Corinthians 11:4-14
4 For, as it is, if someone comes and preaches a Jesus other than the one we preached, or YOU receive a spirit other than what YOU received, or good news other than what YOU accepted, YOU easily put up [with him]. ... For such men are false apostles, deceitful workers, transforming themselves into apostles of Christ. 14 And no wonder, for Satan himself keeps transforming himself into an angel of light.
2 Cor. 9: 7 Let each one do just as he has resolved in his heart, not grudgingly or under compulsion, for God loves a cheerful giver.Notice also that Paul was writing to the congregation when saying "YOU" in his letter to the Corinthians. However, the goverrning body has always managed to apply these verses to outsiders in the world, and especially the clergy of Christendom.
