In his sermon "The Pregnant Virgin," Pastor Nik Adwalpalker encourages the congregation to believe in the Word of God and put it into practice. He uses the story of Mary's miraculous pregnancy to illustrate the importance of faith, even in the face of seemingly impossible circumstances. Pastor Nik also emphasizes the importance of community, drawing parallels between Mary's relationship with Elizabeth and the support believers can find within the church. He concludes by reminding the congregation that they are not alone, and encourages them to reach out to their church community for support.
