Christ is the finisher of our faith in that, through our faith in him, he perfects our faith and perfects us. Through his grace we are saved or, in other words, spiritually finished as to immortality and eternal life. It is upon Christ and his infinite atonement that we should focus our hearts, minds, and strength. He is indeed the light at the “end of the tunnel ”— it is he that the scriptures command us to consider as “the end of your salvation” (D&C 46:7).
“Christ, Who Was the Author and the Finisher of Their Faith”
Compare Hebrews 5:9; Hebrews 12:2. God the Father is the author of the plan of salvation. Jesus, by divine investiture of authority and as the chief proponent of the Father’s plan, is also often referred to as the author of our faith. In some translations of the Bible this term author is translated as captain. Our Savior is indeed the captain of our salvation and the prime mover of our faith and the source of all righteousness. Another word for author is father. Jesus is truly the father or author of the salvation of all who come unto him and are “born again” and thus become his children.
