This text opens up the second main portion of the book of Hebrews. The theology turns into application, the truth into action. And the great value of today's text is it demonstrates the way our minds are to process and engage our lives in the things we have come to know from God's Word. How does Biblical data become living bread?
This text is all about making connections with Biblical statements. It's about forging practical links with the things we have learned previously. You can see the Holy Spirit pulling us along through the mental process. First He calls our minds backward to the things just taught - "...since we have..."(19), "...since we have..."(21) - and then the Spirit presses our minds forward into the logical conclusions - "...let us draw near..."(22), "...Let us hold fast..."(23). And in next Sunday's text, "...let us consider..."(24).
So we start to see a momentum in understanding and application - "Since we know this, let us do that. Since we have discovered this we ought to be doing that." So we are prompted into this rhythm of seeing - "Since this, then that." This is how the Spirit takes us from reading to feeding on the logic of Biblical revelation. This is what turns ideas into bread. You can starve spiritually while reading your Bible if you don't read your Bible aggressively following through on the forged links between truth and application right in the text.
So this text isn't just about certain doctrinal ideas from the letter to the Hebrews. It's also a text about how to read your Bible. It's a text about connecting the dots when you sit at devotions or listen to a sermon. This is the Holy Spirit's way of moving us from a way of knowing to a way of living.
