"For my hand made all these things, thus all these things came into being," declares the LORD. "But to this one will I look, one who is humble and contrite in spirit, and who trembles at My word."
Everything that is created comes from God. There is nothing He did not create.
Psalm 24:1 states, "The earth is tho LORD's and all it contains, the world, and those who dwell in it." Isn't it comforting to know that whomever is in control of the world's governments, or leading our societies, they are stewards that have been put in charge by God. No person, no government, no "ism" (capitalism, communism, socialism) has pre-eminence over the sovereignty of God ... and we are all stewards that have a responsibility to take care of God's handiwork, God's workmanship. It's Theocracy that ultimately rules!
What God ask of us is to be humble and contrite (nakeh in Hebrew, literally meaning maimed or figuratively, dejected ... we need a Savior, after all), to be aware of our need for Him and to act accordingly. In doing such, we can enjoy life and have freedom in serving Him, knowing we are doing God's will by being wise and faithful stewards. He will richly bless those who take care of His creation. After all, everything God created is good! We must worship Him in spirit and in truth. That's what will make life so vibrant and exciting!
Read 1 Timothy 4:4-5, Psalm 50 (especially verses 6, 10-12), John 4:24
Isaiah was telling Israel this truth because they were being swayed by the commercialism of their times, and were acting as if they had a right to do what was right in their own eyes ... they were being hypocritical and not serving the LORD faithfully.
