In the first chapter of Luke’s gospel we are told that he wrote his account, so that Theophilus would have certainty about the words he had been taught (v. 4). Theophilus had evidently heard various things about Christ, and Luke wanted his account to bring him to certainty about them. Luke’s inspired words—Paul quotes Luke as Scripture in 1 Tim. 5:18—are intended by God to bring Theophilus and any reader to confidence about Christ, His work, and other matters related to the Christian faith. God’s Word is powerful to persuade people of its truth. However, as we will see in Luke one, when God gives His word to people, He expects that they respond with belief, not unbelief. Since He is both sovereign and trustworthy, faith is the only appropriate response to what He says. And what a great blessing He always promises to those who believe (Jn 20:29; Rom 10:11)!
