Yes, although we can perceive God's power and loving nature via His creation and moral conscience, most of what we can know beyond that mode of revelation is by means of the Scripture God has gone to a lot of trouble to inspire dozens of writers over thousands of years to create and copy.
I agree that God is not tricky and does not want anyone to be deceived (1Tim. 2:3-4), so every normal person who reads it with an open mind can understand it well enough to be saved. (This is why I am glad my initials include GW :^). However, for those who desire to delve more deeply into the doctrine of election or into the epistle of Ephesians, some of us are participating in a systematic study on the Hermeneutics and Systematic Bible Study threads.
