We ought carefully to examine whether the doctrine offered us is conformable to Scripture, and if not, to reject it. Nothing must be added to the inspired words of God; all that is outside Scripture is not of faith, but is sin.Prolegomena, 2, Work 3, Ascetic (iii).
The Word comes first, and with the Word the Spirit breathes upon my heart so that I believe.Luther's Works, Vol. 54 : Table Talk (Augsburg Fortress, 1999, [c] 1967)
The same decree of God, is the first and principal working cause of all things; it is also before all other causes, in order and time. For with God's decree, his will is always annexed, by which he can willingly effect what he has decreed. And it would be a sign of impotence to decree anything which he could not willingly compass. And with God's will is conjoined an effectual power, by which the Lord can bring to pass whatever he has freely decreed.

the Lord, according to his good pleasure, has most certainly
decreed both every thing and action — whether past, present, or to come — together with their circumstances of place, time, means, and end.
God wills that which is good, by approving it; that which is evil — in as much as it is evil — by disallowing and forsaking it. And yet, He voluntarily permits evil, because it is good that there should be evil.
The Divine Nature is especially in perpetual operation by three attributes
which manifest the operation of God towards his creatures. These are his
WISDOM, WILL, and OMNIPOTENCE
By the nature of the highest genera and of first principles; for those things are known by themselves and are not susceptible (anapodeikta) of proof which cannot be demonstrated by any other, otherwise the thing would go on to infinity. Hence Basil says 'it is necessary that the first principles of every science should be self-evident' (anankē hekastēs mathēseōs anexetastous einai tas archas, In Psalmum cxv homilia, PG 30.104–5). Thus Scripture, which is the first principle in the supernatural order, is known by itself and has no need of arguments derived from without to prove and make itself known to us.
O, grant, that being ruled by thy Spirit, we may surrender ourselves to thee, and so acquiesce in thy Word alone, that we may not deviate either to the right hand or to the left, but allow thee alone to be wise, and that acknowledging our folly and vanity, we may suffer ourselves to be taught by thy Word.Lecture 36 on Jeremiah
Since the entirety of Holy Scripture is the word of the Lord, no testimony could possibly be better, more certain, or more efficacious. For if God, who cannot lie, has spoken something in his own Scripture, which is itself a mirror of his will, then it is true.On the Truth of Holy Scripture, 1.15
Scripture is the foundation of every Catholic opinion, and within it resides the very salvation of the faithful. Moreover, it is the exemplar and mirror designed to examine and extinguish every sort of error or heretical evil. Surely even a small error in this principle could bring about the death of the church.On the Truth of Holy Scripture, 1.1-2
