When we say His works, we speak of the activities of the Triune God in relationship to His creation in general, and His people in particular. In the above passage, we see three distinct areas of God's overall work of relating to His people - grace, love and communion. All three are one great work, with three incredible properties. This work of the Triune God, in anchoring the Christian, is a loving, gracious communion. Thus the work of God here points us back to it's author - who being One in existence, acts within that existence as Father, Son and Holy Spirit.
2. God's names
The names of God point to His character. Scripture mentions hundreds of them. In this passage, we see When we speak of His names, His names help us identify various features of His character. It is not enough just to know the works of God, but as Psalm 103:7 states, there is that deeper level of know God, namely His ways. I have found the names of God to be helpful, since He often revealed His names in contexts where He was revealing His character. In this text we see three: Jesus Christ, God the Father and the Holy Spirit. Thus God is One in character, and three in identity. No conflict exists within God.
3. Adoring God's nature means knowing Him, not comprehending Him
After we have begun with God's works, and proceeded to note His names, we can finally begin to know God. When we do this, we realize that our goal of comprehending God will never be met, since God's glory is beyond comprehension. We can legitimately know God, but never comprehend Him. I can for instance know how a light works when I enter a room - simply flick the switch. However I may not fully comprehend all the laws of physics, mechanics and engineering that it takes to make the switch work. In a much more profound way it is the same when it comes to developing a deeper appreciation for the Trinity. The only proper response is worship and adoration (Psalm 100).
