"and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work." 2 Timothy 3:15-17
Q. 3. What do the Scriptures principally teach?
A. The Scriptures principally teach, what man is to believe concerning God, and what duty God requires of man.
Has anyone ever asked you "What is the Bible about?" Or have you asked that question? The answers we hear and the answers we give can vary; from a book of made up stories to a book of morals, a book with too much symbolism to the Sunday school answer "a book about Jesus."
Is there one answer? Can we come to a consensus? The Divines did: what man is to believe and what man is to do.
As reformed folks, we cringe at the idea of "duty." "God is sovereign, I can't do anything to please Him, I'm too depraved." But the Bible doesn't shy away from this reality; God commands us to believe and obey Him (Micah 6:8).
How, then, does the Bible marry these two ideas? The answer lies in the history of redemption. From Genesis to Revelation, we see God entering into relationships with His people, and these relationships are built on the promises of God: "I will be your God and you will be my people" (Jeremiah 30:22).
"I will be your God": what man is to believe concerning God. "...you will be my people": what duty God requires of man.
We see the apex and perfection of this promise in the Lord Jesus Christ. To see Jesus is to see the Father (John 14:9). Those whom Jesus loves, the Father loves (John 16:27). The Lord Jesus Christ is God with us (Matthew 1:23), especially now by His Spirit, who is God dwelling in us (Ephesians 1:13) and because of this reality, we are now a people who live by faith in the Lord Jesus Christ (Titus 2:11-14). This is what the Scriptures primarily teach. This is what the Bible is about.
