Many churches throughout the world use a Bible reading schedule called a "lectionary." It's just a fancy word meaning "selected readings." Posts like this reflect on the readings for an upcoming Sunday or other Church holiday, as found in the three-year lectionary.
I have a friend who, as a pastor and a professor, would often draw atriangle to represent God. The symbolism at first suggested an argument for the Trinity, and we can certainly do that. However, my friend would then put the letters “s, w, g” on his drawing, one at each point of the triangle. Psalm 100 identifies God in this way.
S - He is the sovereign God. He can do what He wants. In verse 3 we see he is the creator and owner of all. He exercises rule over his creation. He has the power to accomplish all he wants.
W - He is the wise God. He knew how to create everything. He is faithful. He does not act in a random or capricious manner. In this, He stands apart from all the other deities known in our world.
G - He is the good God. He is blessed by His people because he is good. There’s no evil in God.
Of course, there are many other attributes we could identify in God. If I were a systematic theologican I could probably list a lot of those characteristics off the top of my head. But those three - God as sovereign, wise, and good, will keep us in order for a long time. The three attributes are all necessary. With any missing, God is frightening and we have no reason to hope. But the sovereign, wise, and good God is the one we praise. He is truly the Lord of our Psalm.
