Well here's the thing...if all the people contesting for power are the same people your voter's card would be useless. Say for example, 2019 is coming, elections will hold in Nigeria and people are expected to go vote right? But who are we voting for if not the same class of people? Same stories, same promises, same agendas just recycled people. But if christians participate in politics and we put out a different breed of candidates, a breed of candidates with a renewed mindset, then our voters' card will command a change...the right change. If not, it would be like casting your pearls to the swines. I think that's what she means...
