Human beings acknowledge and recognize God in terms of God's attributes that are revealed in the Bible.
It is impractical to describe all of God's attributes, so we shall focus on only two.
1. God is holy.
God's holiness means that He is worthy of worship, and devotion because He has righteousness and goodness that surpasses that which can be found in any other created being.
In the prophet Isaiah's vision, he saw holy angelic beings (who cannot be charged with any wrongdoing) continually worshipping God as holy.
2. God is merciful and kind.
Although God is holy and must punish wrongdoing, He is also merciful.
In Lamentations, the prophet Jeremiah says "It is of the LORD's mercies that we are not consumed because His compassions fail not; they are new every morning; great is Thy faithfulness".
The prophet acknowledges that if God had not been merciful, the nation of Israel would have perished because of wrongdoings.
