The book of Luke

In Luke 1:1-3 teaches us that the New Testament Scriptures are on the same authoritative level as the Old Testament Scriptures. (Luke 24:25-26, 2 Peter 3:14-18, 2 Timothy 3:16-17) 

The eyewitnesses and servants of the Word mentioned in Luke 1:2 are none other than certain saints in the Old Testament. (John 8:56, Hebrews 11:13, 1 Peter 1:10-11) 

Luke understood that the testimony of an eyewitness was crucial. (Acts 1:21-22, 1 Corinthians 15:3-8) 

Luke is written for the person who desires to love God. (Luke 1:3) 

Luke embraced excellence in his service to Jesus Christ.

Luke had a reason for writing this book. (Luke 1:3-4, Matthew 27:50-51, Mark 15:37-38, 1 John 5:13, John 20:30-31, Hebrews 4:11-13, Matthew 24:35)
