In partnership with parents, public schools, churches and ministry partners, School Time Bible Ministries (STBM) provides off-campus Biblical teaching for public school students. School Time Bible Ministries provides students the opportunity to embrace the Gospel, to grow in Christian maturity, and to apply Biblical principles in the many choices they must face in their lives.


By God’s grace and guidance, School Time Bible Ministries will provide an opportunity for every public school student to voluntarily participate in an off-campus Bible education class during their elementary, middle and high school years.


We believe that the Bible, including both Old and New Testaments, is the true Word of God and is the sole rule of faith and practice. We believe in one God, the creator and sustainer of the universe and all that is therein, who is eternally existent in three persons: the Father, the Son, and the Holy Spirit. We believe in Jesus Christ, the only begotten Son of God, who was incarnate by the Holy Spirit of the Virgin Mary. We believe that He suffered, died and was buried; that He rose bodily from the dead, atoning for the sins of mankind by His shed blood on the cross. We believe that He will return to judge the living and the dead. We believe in salvation by God’s grace through faith alone in Christ, the regenerating work of the Holy Spirit and life everlasting.
