Great Question

     Why doesn't God show Himself to us? Was a question I got from one of my Good News Club kids. Kids ask such simple but such profound questions sometimes. This particular kid has a mom who is Buddhist and decided to accept Jesus last year at Good News Club.
     So then why doesn't God show Himself to us? Well, if he did we would all die immediately from the presence of pure holiness, righteousness, justice, and Godness. So incineration, kaput, kapooie! We as sinners would not survive that kind of revelation of God to His creation.
      Kid: What about Jesus?
      Me: Well, Christ kept at bay that part of himself that was able to destroy all of human kind. He kept the fullness of his glory and power in check so that we would not be destroyed by His presence. Why? Because he can.
     If He hadn't done that there would have been no drinking of God's wrath and no promised Savior. So in a sense he did this because he had to in order to pay the price for our salvation. (This is close but probably not word for word to how I answered the question at Good News Club. It was pretty hard core like that though.)
     Since answering the question above live however I have had a chance to really look at the question and think about it as Old Testament stories come up in my Church and in my devotional life. Sometimes the Bible can get really big and complicated.
     God showed Himself to many in the Old Testament including but not limited to these specific times:
 Abram -Gen. 12:7 'Then the LORD appeared to Abram and said, “To your offspring I will give this land.” So he built there an altar to the LORD, who had appeared to him.'
 Isaac -Gen. 26:2 'And the LORD appeared to him and said, “Do not go down to Egypt; dwell in the land of which I shall tell you.'
 Jacob -Gen. 28:13 in his dream and again in Gen. 35:9,10 'God appeared to Jacob again, when he came from Paddan-aram, and blessed him. 10 And God said to him, “Your name is Jacob; no longer shall your name be called Jacob, but Israel shall be your name.” So he called his name Israel.'
 Moses -Ex. 3:2 And the angel of the LORD appeared to him in a flame of fire out of the midst of a bush. He looked, and behold, the bush was burning, yet it was not consumed.
 Gideon -Judg. 6:12 And the angel of the LORD appeared to him and said to him, “The LORD is with you, O mighty man of valor."
 Samson's parents -Judges 13
 Samuel -1Sam. 3:21 And the LORD appeared again at Shiloh, for the LORD revealed himself to Samuel at Shiloh by the word of the LORD.
 Solomon -1Kings 3:5 At Gibeon the LORD appeared to Solomon in a dream by night, and God said, “Ask what I shall give you.”, 1Kings 9:2 the LORD appeared to Solomon a second time, as he had appeared to him at Gibeon.
 And more times throughout the Old Testament.
God was not just interested in letting "people do their thing" and not getting involved. He made us to be in relationship with him.
     So why doesn't he appear to us today? One reason probably has to do with us having the revealed word of God in the form of the Bible today. He does not need to show Himself because He already has.
     He still is a very personal God and wants us to have a relationship with Him like Abraham or Moses did but He does not need to physically be there in order to do that. He wants us to pursue Him and be willing to give up ourselves for Him. He wants us to come as we are, whether that means you are broken and needing to run to Him right now or whether you are having a good day and just need to take a moment to remember who it was who made the day.
     It's hard for me to wrap my mind around the fact that the God who created the cosmos and thought of every little detail down to the smallest sub-particulate piece of matter that's out there would even be interested in me. But He is. The least I could do is be interested in getting to know Him.
     Don't know if that's much of an answer. It's something. If I can come up with something better I'll be sure to post it but for now that's my answer. It's different from my original answer, not that the original one was completely wrong but I didn't take into account that God had come down and talked with different people before Christ came and lived a life among us.
