Q.4: What is the Word of God?
A. The Holy Scriptures of the Old and New Testament are the Word of God, and the only certain rule of faith and obedience.
"All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness" (2Timothy 3:16; NASB).
“having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone” (Ephesians 2:20; NASB).
