In between the first and second letter of the Apostle Peter we read two Psalms and the third chapter of Daniel.
Psalm 145, a Psalm of Praise, of David. In an acrostic fashion David praised God for his fame, glory and for His goodness; for his kingdom and His providence, and most of all for his saving mercy.
Psalm 146 begins the five final songs in the Book of Psalms, known as the Hallelujah Psalms. This one gives praise to the Lord for creation, for what He is doing and will do forever.
Daniel 3 tells about the image of gold that all had to worship, and the fiery furnace prepared for the three Hebrews that refused. From Sunday School we all know how that went.
