Psalm 100 calls all people to make a joyful shout and sing to God, who created humanity and cares for them as a shepherd cares for his flock. It encourages people to enter God's presence with thanksgiving and praise because God is good, merciful, and faithful forever. Ephesians 6:10-11 instructs believers to be strong in God's power so they can withstand the devil's schemes by putting on the full armor of God.

2. Psalm 100
A Song of Praise for the LORD’s Faithfulness to
His People
A Psalm of Thanksgiving.
100 Make a joyful shout to the LORD, all you lands!
2 Serve the LORD with gladness;
Come before His presence with singing.
3 Know that the LORD, He is God;
It is He who has made us, and not we ourselves;[a]
We are His people and the sheep of His pasture.
4 Enter into His gates with thanksgiving,
And into His courts with praise.
Be thankful to Him, and bless His name.
5 For the LORD is good;
His mercy is everlasting,
And His truth endures to all generations.

3. Ephesians 6:10-11
The Whole Armor of God
10 Finally, my brethren, be
strong in the Lord and in the
power of His might. 11 Put on
the whole armor of God, that
you may be able to stand
against the wiles of the devil.
