The Goal

Dr. Joseph Kostelnik founded Gospel Truth Ministries (the parent ministry of Prophetic Voice Publications) at the leading of the Lord. He envisioned a ministry that would equip other ministers to continue the work of the Kingdom of God.

Through the various books and sermons and messages he has written and preached over the last 30 years, he has done his best in cooperation with the Holy Spirit to bring this to pass.

The Faith

Gospel Truth Ministries and its publication outreach, Prophetic Voice Publications, have always used the Apostles' Creed to define their fundamental faith in God:

  • I believe in God the Father, Almighty, Maker of heaven and earth:
  • And in Jesus Christ, his only begotten Son, our Lord:
  • Who was conceived by the Holy Spirit, born of the Virgin Mary:
  • Suffered under Pontius Pilate; was crucified, dead and buried:
  • He descended into hell:
  • The third day he rose again from the dead:
  • He ascended into heaven, and sits at the right hand of God the Father Almighty:
  • From thence he shall come to judge the quick and the dead:
  • I believe in the Holy Spirit:
  • I believe in the holy catholic (universal) church:
  • The communion of saints:
  • The forgiveness of sins:
  • The resurrection of the body:
  • And the life everlasting. Amen.

This ancient and succinct recitation of the fundamentals of the faith calls all believers together, to work in unity toward the propogation of the Good News of Jesus Christ.
