“Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.” —Hebrews 12:2
The incarnation is that glorious truth of God becoming a man, living a perfect, sinless, righteous life, enduring unspeakable torture at the hands of sinful men, enduring unspeakable punishment through the wrath of God’s exacting justice, submitting to death itself, rising again the third day, appearing before a multitude of witnesses, ascending to the right hand of God, ruling and reigning in the hearts of men by His Spirit, and sealing their redemption until the return of Jesus Christ in that glorious day.
Jesus Christ is the Author and Finisher of faith, the First and the Last, the Origin and Completion, the Alpha and Omega.
As a Man, perfect and blameless, He stood upon the planet as the only One ever whose righteousness could stand without shame in the very presence of God the Father. As the holy God who dwelt among men in the form of a Servant, He effected and perfected all works in Himself, by Himself, and through Himself, and therefore was, is, and evermore shall be sufficient to save the least unto the greatest of all those who trust upon Christ alone.
As Author of faith, salvation is all of grace. The vilest offender, even one persecuting Christ Himself, is not beyond the reach of this salvation; neither is the most pious of men beyond the grasp of saving grace; neither is the most indifferent mind nor the filthiest heart beyond Christ’s redeeming grace.
As Finisher of faith, sanctification unto glorification is also all of grace. The soul saved by grace still requires all of grace to glorify God in all he or she thinks, says, and does. The most physically fit person does not require any less grace than the most physically infirmed. The wisest among believers requires as much of God’s grace to expound the simplest truth as the most unlearned needs to grasp that same truth. The noblest deed requires all of grace as does the most common task. It is all of grace from beginning to end, and thereby, does God receive the glory.
