T. Austin-Sparks emphasizes the concept of being 'Pioneers of the Heavenly Way,' illustrating that true believers are called to live as strangers and pilgrims on earth, seeking a better, heavenly country. He explains that the relationship between heaven and earth is foundational to understanding our spiritual journey, where our education and purpose are rooted in heavenly realities. The sermon highlights the inward transformation that occurs when one is called from heaven, leading to a sense of conflict with worldly values and a longing for the divine. Sparks encourages believers to embrace the cost and challenges of this pioneering path, reminding them that their ultimate destination is a city prepared by God. He concludes by urging the congregation to cultivate a spirit of pilgrimage, always seeking the deeper realities of their faith.
