The apostle Paul tells us that there are two and only two kinds of people in this world. There are those who, because of their fall in Adam, serve and worship the creature rather than the Creator, and there are those who, because of their redemption from the fall through Jesus Christ, have learned to serve God their Creator and Christ their Redeemer rather than the creature.
Men of the second group are not, of themselves, any better than men of the first group. It is not because of superior wisdom found in themselves that they of the second group have learned to serve and to worship God. It is, rather, because they have been born of the Spirit, born from above, that they would now dedicate themselves and their all to the Father, the Son and the Holy Spirit.
– Cornelius Van Til, The Sovereignty of Grace p.7
