Having a missional heart is an essential marker of a growing disciple. Our concern cannot simply be for our own spiritual health and our own growth. The most basic definition of a disciple is “a learner.” To be an effective disciple, we should increasingly become more like our teacher. Our teacher cares deeply for the lost. He loves them so much that He came to earth to save them. He has done it for you and longs to do it for others as well.
