The Holy Scriptures

God has spoken: Scripture is the only rule of faith and life.

All Scripture is God-breathed and is useful for instruction, for conviction, for correction, and for training in righteousness, so that the man of God may be complete, fully equipped for every good work.
2 Timothy 3:16–17

Above all, you must understand that no prophecy of Scripture comes from one’s own interpretation. For no such prophecy was ever brought forth by the will of man, but men spoke from God as they were carried along by the Holy Spirit.
2 Peter 1:20–21

The Law of the LORD is perfect, reviving the soul; the testimony of the LORD is trustworthy, making wise the simple. The precepts of the LORD are right, bringing joy to the heart; the commandments of the LORD are radiant, giving light to the eyes. The fear of the LORD is pure, enduring forever; the judgments of the LORD are true, being altogether righteous. They are more precious than gold, than much pure gold; they are sweeter than honey, than honey from the comb. By them indeed Your servant is warned; in keeping them is great reward.
Psalm 19:7–11

For the word of God is living and active. Sharper than any double-edged sword, it pierces even to dividing soul and spirit, joints and marrow. It judges the thoughts and intentions of the heart.
Hebrews 4:12

For just as rain and snow fall from heaven and do not return without watering the earth, making it bud and sprout, and providing seed to sow and food to eat, so My word that proceeds from My mouth will not return to Me empty, but it will accomplish what I please, and it will prosper where I send it.
Isaiah 55:10–11

Sanctify them by the truth; Your word is truth.
John 17:17

For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished.
Matthew 5:18
