Make a joyful noise to the Lord, all the earth!
Serve the Lord with gladness!
Come into his presence with singing!

Know that the Lord, he is God!
It is he who made us, and we are his;
we are his people, and the sheep of his pasture.

Enter his gates with thanksgiving,
and his courts with praise!
Give thanks to him; bless his name!

For the Lord is good;
his steadfast love endures forever,
and his faithfulness to all generations.

Psalm 100:1-5

Worship is a word that we use so frequently that we might be tempted to grow cold to it’s meaning.  What do we do when we worship?

The word worship comes from an old English word weorthscipe which meant to shape the worth of something. It has to do with declaring the worth or worthiness of something, or paying respect and reverence. So, when we worship God, we declare God’s worthiness, and we pay him respect for who he is.

But, who is God, and what is he like? What are his attributes, his characteristics? The Westminster Larger Catechism states, “God is a Spirit, in and of himself infinite in being, glory, blessedness, and perfection; all‑sufficient, eternal, unchangeable, incomprehensible, everywhere present, almighty, knowing all things, most wise, most holy, most just, most merciful and gracious, long‑suffering, and abundant in goodness and truth” (WLC #7).

This answer lists some of the attributes and characteristics of God – what makes God God. As we look to these aspects of God’s character and what they tell us about him, we must remember that all we can know about God is what he has revealed to us. It is impossible for our finite minds to fully understand our infinite God. This is what is known as the incomprehensibility of God. It does not mean that we cannot know or understand anything about God. It just means that we cannot know and understand everything about him. The reason for this is what is known as the Creator/creature distinction.

Several theologians and teachers have written books and essays on the attributes and characteristics of God. The list of attributes is rather long, but some can be grouped together. For instance, we can speak of the fact that God is self-existent, self-sufficient, infinite and eternal. God has always existed, and he will always exist, with no need for anyone or anything to make him who he is. He is solitary and triune. As the Creator and sustainer of the universe, he is sovereign and supreme. He is righteous and holy in all that he does. He is separate from us and transcendent, but also immanent and with us at all times. He is immutable (unchanging) and faithful in all things. He is patient and long-suffering. He is both loving and wrathful. God is good, gracious,  and merciful toward his people. He is present in all places, all-powerful, all-knowing, and wise.

This is the God who made us. This is the God we worship.
