Jesus once said about a group of people “they know not what they worship” (John 4:22). I think this statement holds true for many people. So many don't really know the god, or even much about him, that they claim to worship. If a person doesn't know the god they are worshiping, how can they know what pleases him? Even greater than that, what is this god like? What is he not like? Can you even know him? These are questions that every worshiping person should ask. If these questions have no answers in the soul of the worshiper then worship will be completely arbitrary to the worshiper. At best, their worship will be unpleasing to their god. At worst, their god doesn't exist and it's all just a figment of their imagination.
Thankfully, the Christian God has revealed himself to be true and knowable. But not only this, he has revealed the type of worship that is pleasing to him. If you have ever studied the attributes of God, or what they call Theology Proper, sometimes you just have to sit down in awe. I think very few people have thought deeply about God. Some see him as a principle that if they fulfill their part, God will do his. Others see him as nothing different than a kind old man. However nice this may seem to someone, it's just not reality.
Have you ever thought how different God is from us? Some theologians have grouped certain attributes of God together and called them the incommunicable attributes of God. These are attributes that we have nothing comparable to. They are attributes so different that we really can't even find degrees of these attributes in any part of creation. One of these attributes would be eternality. Nothing has this attribute but God. Everything that we know of, apart from God, had a beginning. If there is something that truly is eternal then it must be a part of who God is. We may have in our consciences the impossibility of everything truly coming to an end, but clearly things had a beginning. Who can imagine what death is like? And if you can, you still can't imagine a true end of all things because, well, you're still thinking and imagining aren't you? Whether you can imagine it or not, it's indisputable that you had a beginning. God isn't like that; he had no beginning. He is eternal. If this incommunicable God hadn't been communicated to us by revelation, we hardly would have imagined him.
Here is another one. God is completely independent. Can you think of anything that is truly independent? You won't be able to unless you are thinking of God. Since everything had a beginning, obviously, it was dependent on God creating it. But even a part of that, nothing in this world is completely independent. Everything in this world or universe is dependent on other minerals, gases (try breathing without oxygen), other people, the sun, and the list could go on. Even atoms are dependent on an electric force making the positive and negative charged materials come together. Would we have ever imagined something or someone who was completely independent of all things without it being revealed? We could go on but I just want to give you an idea.
There are also attributes that theologians have labeled the communicable attributes of God. These are attributes that you can find degrees of them in the creation. Some examples might be knowledge, wisdom, or love. You can find these in people yet in a degree so small in comparison to God it's nearly incalculable. We have seen people with knowledge on a topic before. Yet God's knowledge is infinite and undetained. The comparison of the most knowledgeable man ever between God is nearly incomparable yet there is enough comparison that we can formulate an idea of what it is to have perfect knowledge. I think this principle stands true with any attribute of God that you can find it's imprint in his creation.
It would almost seem that God is so different or “wholly other” than us, that we couldn't possibly know him. The bible teaches God is so high and lofty and he humbles himself to even look at his creation (Psalm 113:6). I would guess without God self-disclosing himself to us, the best we could have come up with is “I think there is something bigger than me out there.” Thanks be to God we have a much better picture of who he is that just something bigger and greater than us. If you were to compare it to all of who God is, we hardly have any knowledge of God yet what God has revealed to us through the Living Word is weighty enough to make a man fall prostate and weep aloud for joy, terror, awe, and greatness in the presence of the great God who simply is the I AM.
The unthinkable thing is that Christian doctrine doesn't even stop there. We don't merely claim to have revelation of who God is. We claim that this God humbled himself and became a man, willingly allowed his own creation to crucify him, and resurrected the third day all to rescue us. As mind numbing as that might be, to be true to the Bible we can't even stop there. This God has decided to come and make his abode with us.
Just the thought that we can know something about God, being as infinite and great as he is, should put us in worship and thanksgiving. Yet for the born again Christian, just the knowledge of who God is in a theological sense barely scrapes the surface of what we have in Christ. We don't merely know about God in a theological sense, we can know him in a personal, experiential sense. Not merely do we have God revealed to us but we can have this God revealed in us (Gal 1:16).
For the Christian, it's not that difficult to think of something to be thankful for.
Psalms 113:5-6 Who is like unto the LORD our God, who dwelleth on high, who humbleth himself to behold the things that are in heaven, and in the earth!
1Cor 1:30-31 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: that, according as it is written, He that glorieth, let him glory in the Lord.
1Ti 6:15-16 ...the blessed and only Potentate, the King of kings, and Lord of lords who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
