Worship of God is important
Genesis 8:20 Then Noah built an altar to the LORD, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar.
Its fitting, the 1st action done after getting off the ark, was worship. Noah sacrificed to the LORD. He used only what the LORD provided, of every clean animal. That was a lot of sacrificing and how did all those couped up animals, for a year, not run away? He offered back to God simply what God blessed them with. Worship of the LORD is our highest calling. When we fail to give Him glory, we only hurt ourselves. We cant handle the glory that belongs to Him alone.
