From Grace Bible Church constitution:
We believe there is but one living and true God, eternally existing in three Persons – God the Father, God the Son, and God the Holy Spirit. These Persons are the same in substance, and equal in power and glory. (Gen 1:26, Matt 28:19) We consider this belief to be a definitive doctrine of the Christian faith; it is required of all members of Grace Bible Church.
Therefore, we strive to give all honor, worship, and obedience to the Triune God alone, and reject any and all claims of obedience or worship that rival that of the Triune God.
We didn’t stay for long on a doctrine-based consideration of the Person and Nature of the Tri-une God, but instead jumped right into Isaiah 6. The chief question that we sought to answer as we unpacked this chapter: What should a person expect as he or she comes to church to worship this holy God? Such a person can expect…
…to be confronted by the collision of the seen and unseen world, and the presence of a uniquely holy (morally perfect in all of His attributes and nature) God. (1-4)
…to be convicted of sinfulness and failure. (5)
…to be graciously cleansed and forgiven of sin. (6-7)
…to be called to obedience in the pursuit of a completely new direction and purpose in life—serving God and calling the surrounding culture into a restored relationship with Him. (8-13)
