A key element of God's character is love, which David describes as the first example. As he points out, God's love knows no bounds. It encompasses both the heavens and the lost world of sinners. In addition to God's love, His faithfulness knows no bounds. In David's description, this extends to the clouds. There is no failure on God's part in providing for His creatures. Every promise He makes, He keeps.
Unregenerate persons are not capable of understanding this knowledge of God since they view the wisdom of God as foolishness. As a matter of fact, God's foolishness is wiser than man's wisdom, and His weakness is greater than man's combined strength. However, such understanding is sweet and strengthening for the sanctified soul since true knowledge of the Holy One arises from spiritual discernment.
Knowing the Lord quickens our hearts, comforts our souls, informs our thoughts, and brings joy and peace into our lives. As the psalmist suggests, may our hearts be lifted in thanksgiving and praise in every moment of our transient lives because God's faithfulness extends beyond the clouds, His loyalty reaches into the sky, and His saving grace reaches into the eternal ages to come.

Dear Heavenly Father, Your precious promises regarding Your nature and character give my fainting soul many reassurances. You have expressed Your love, faithfulness, might, and justice through the person of the Lord Jesus. My heart is full of gratitude to You for sending Him to die on the cross and rise to new life so I can be brought into fellowship with You. It is my prayer that I would be bold in sharing the truth of Your magnificence with all You place in my path today. 
In Jesus's name I pray. Amen.
