2 Timothy 3:15-17 New International Version (NIV)

¹⁵ and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. ¹⁶ All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, ¹⁷ so that the servant of God^[a] may be thoroughly equipped for every good work.

Hebrews 1:1-3 New International Version (NIV)

God’s Final Word: His Son

1 In the past God spoke to our ancestors through the prophets at many times and in various ways, ² but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. ³ The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.

Hebrews 4:12 New International Version (NIV)

¹² For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
