In my own opinion I would say Pastor's preach prosperity this days because to me it seems they have lost the essence of their calling. To an extent I will say how many of them are really called to be a pastor? Many of them are their for self glorification and self gratification. When you look closely, You will notice that apart from politics in Nigeria, another lucrative business is the church business and if you are good at telling the people what they want to hear and not what they must hear, then be sure they will continue to sow a seed in the pastor, bless the pastor while the pastor continue to progress and the church member wallow in abject poverty.(Some). With some exception among the Nigerian Pastor, I will tell you that most are fraudulent. Pastors don't want to loose their members therefore they seldom talk about salvation rather they preach about the need to amass wealth simply because they know it will flow back to them via the members. Any way I will like to say people should be vigilant cos we are in the endtime.
