This is an excellent clip from my friend Brett Kunkle. I have dealt with this many times and written about the issue on this blog. Also, let me add a few points:
The skeptic constantly assumes that if they could just see God directly or if God would give them an unmistakable sign that He is there, they would bow their knee and follow Him. Sadly, this is misguided on several levels. God declares, “You cannot see my face, for no one may see me and live” (Exodus 33:20). However, there seems to be other texts that indicate people did see God. Even in Exodus 33:11 Moses speaks to God “face to face.” Obviously, “face to face” is a figure of… speech which means they were in close communion or conversation.
Also, in Genesis 32:30, Jacob saw God appearing as an angel. But he did not truly see God. In Genesis 18:1, it says the Lord appeared to Abraham. Obviously, there are other cases where God appears in various forms. But this is not the same thing as seeing God directly with all His glory and holiness. It is evident that people can’t see God in all His fullness (Exodus 33:20). For if they did, they would be destroyed. One of the most important themes of the Bible is that since God is free and personal, that he acts on behalf of those whom he loves, and that his actions includes already within history, a partial disclosure of his nature, attributes, and intensions. Revelation is a disclosure of something that has been hidden– an “uncovering,” or “unveiling.” There are three things are needed for a revelation to take place: God, a medium, and a being able to receive the revelation.
Jesus is the ultimate revelation of God and he shows the world who God is (Heb. 1:1).
