I told a colleague that I would post the key points that I noted during John's teaching:
It's important to pursue an accurate interpretation of the Scriptures.
A true understanding of the Scriptures:
reveals the true nature of God
reveals the true nature of man
Many people don't like the clarity of the Scriptures, so they deny it, preferring to stay in the darkness.
Three approaches to the truth:
1. Cognition - to know, to understand "the renewing of your mind."
2. Conviction - to believe, when you believe it to the point that you take action
3. Affection - to know it and to believe it and to love it - to delight in it (God's Law)
(My note, if you are affected, then it will be visible in your life; you will put off the old ways and take on the new.)
Watch out for confusion, especially from those who would promote obscurity and perpetual uncertainty. The Bible is very clear.
Common challenges to the Scriptures
Inspiration, inerrancy, authority
If you don't read it, you can't understand it. if you can't understand it, you can't know it.
Sorry about the lack of references. John provided them, I was writing fast.
Update: I just checked the GTY web site. Looks like they've made some significant updates to the web site, including a video that tells the story of the Grace to You radio ministry. A few years ago, we took our homeschool group to tour the world headquarters of Grace to You. It was neat to see the facilities and meet the people behind the radio ministry.
