For those who say natural theology is not a 'salvation' issue.
From Bray, 2012 God is Love: A Biblical and Systematic Theology, p. 27.
"Natural
theology has its importance and is taken seriously in the Bible, but
it is a preparation for the gospel and not a substitute for it. It gives people enough knowledge for people to be able to respond to the message of salvation, but not enough to work it out for themselves."
Emphasis, mine.
The
days of Genesis do this by placing creation and God's direct action in
the history that we are in and showing that God is close, active in
history, communicative, and personal and we are connected to him by his word.
