......”Always make scripture itself your primary source”......
As much as I appreciate any number of extrabiblical sources, they are indeed assistants to the absolute authority which alone is inspired and inerrant: Scripture
“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 Tim. 3:16–17)
Scripture is enough because the work of Christ is enough.
The question always is whether we will open our Bibles and bother to listen.
Amen.
