"As it is written:
'None is righteous, no, not one; no one understands; no one seeks for God.'"
- Romans 3:10-11
"It is foolish to structure worship for unbelievers who are seeking after God when the Bible tells us there aren’t any seekers. It manifests a failure to understand the things of God. If we understood the things of God, we would know that there is no such thing as unconverted seekers. Thomas Aquinas was asked on one occasion why there seem to be non-Christians who are searching for God, when the Bible says no one seeks after God in an unconverted state.
"Aquinas replied that we see people all around us who are feverishly seeking for purpose in their lives, pursuing happiness, and looking for relief from guilt to silence the pangs of conscience. We see people searching for the things that we know can be found only in Christ, but we make the gratuitous assumption that because they are seeking the benefits of God, they must therefore be seeking God. That is the very dilemma of fallen creatures: we want the things that only God can give us, but we do not want him. We want peace but not the Prince of Peace. We want purpose but not the sovereign purposes decreed by God. We want meaning found in ourselves but not in his rule over us. We see desperate people, and we assume they are seeking for God, but they are not seeking for God. I know that because God says so. No one seeks after God."
- R.C. Sproul from his commentary on Romans (pp. 89-90)
