PSALM 95 Verses 1 and 2

Psalm 95:1-2 NIV
Come , let us sing for joy to the LORD;
       let us shout aloud to the Rock of our Salvation.
Let us come before him with thanksgiving
       and extol him with music and song.

In the wholehearted prayer described in Psalm 95:1-2
we are invited to throw ourselves into exuberant ,
heartfelt expression of our joy in His presence
and fully express our thankfulness, in music and song.
It is clearly not appropriate to participate half-heartedly
in public worship and praise.

Psalm 22:3 AV
But thou art holy, O Thou
     that inhabitest the praises of Israel.

1 John 2:27 NLT
But you have received the Holy Spirit,
and He lives within you,
so you don't need anyone to teach you what is true;--
For the Spirit teaches you all things,
and what he teaches is true.
So continue in what he taught you,
and continue to live in Christ.
