Psalm 95

There is a stark contrast displayed between the first 7 verses and the last 4. The readers/singers are encouraged to raise their voices as an expression of praise for who God is and all that he has done. Ine of the great acts of his kindness and provision can be seen in the 40 year deliverance and provision of Israel. In those 40 years the people repeatedly ignored, rejected, and tested God. If we fail to recognize who God is and all of the wonders that he displays for his glory, we may become hardened like that generation of Israel. A hardness that will leave us ignorant of God's nature and empty of his blessings.
It only took a minutes to read this psalm.
