Brethren, what we have in these three verses is a general principle in which God challenges us to consider, to compare, all of the material idols, which are so easily seen, to Him.
Remember is a very important word to a true, spiritual religion. Remember that God's counsel stands. When He says something, it is so. It happens. God gives plenty of evidence to demonstrate that He can be trusted. Being able to see God and have faith is the result of seeing the evidence by which God demonstrated both Himself and His purpose in the former things.
Isaiah 46:9 says, Remember the former things. That is what David did. That is what Shadrach, Meshach, and Abed-Nego did. They remembered the former things. God demonstrated Himself in the former things - not only Himself, but also His purpose. We have to remember. But, brethren, it is really reinforced and built through obedience to His counsel in the present and seeing from one's own experience that it truly does stand. And then, one can see God!
