(And the rest of Luke, too) if you look at how much Scripture Jesus knows and uses in moments of temptation or to direct people to the Good News, you see a pattern emerge: we should love God and God’s Word more! We should be trusting Him to have the words of life and then follow them and believe them!
What if I told you that all the good news about Jesus was already in the Bible before Jesus was even born? How to live; how to forgive; God’s purpose for this earth and ya, all there… we just didn’t see it or understand it. Then Jesus comes and shows us God’s law and Way lived out. We see His heart and desire for us! It’s hard to believe, but that’s just what Jesus’ plan of action was. He utilized all at His fingertips, what we call the Old Testament. It was there the whole time. Love God and His Word!
