1 Thessalonians 2:13 And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
So the point of 1 Thessalonians 2:13 is that there is a right way to accept or welcome the teachings of the Bible when we receive it. And the right way is to accept it for what it really is, the very word of God. We should embrace it and welcome it as the word of God, because it is the word of God. It is God’s truth and has God’s authority. It is the rule for all other claims to truth and the rule over all other authority. We should embrace it that way.
Now how do we do that? What does it look like to welcome the Scriptures as the word of God? I have a three-fold answer from the context of Thessalonians and a five-fold answer by implication based on what the Bible says elsewhere about how to use it.
