The Son of Man Came to Seek and Save the Lost

Because true faith "is not only a certain knowledge, whereby I hold for truth all that God has revealed to us in His Word; but also a hearty trust, which the Holy Ghost works in me by the Gospel..." (Heidelberg Catechism Q. #21) it is extremely important to know the Gospel. Thus, the Holy Spirit moved Luke to write another account of the person and works of our Lord Jesus Christ, that we may "know the certainty of those things in which you were instructed."
