“I will praise You , O my LORD my God, with my whole heart,
 And I will glorify Your name forevermore.”  Psalm 86:12 

Praise refers to words or actions that give honor to God.  Webster defines it  as, the grateful homage in words or songs as an act of worship.
Vines Complete Expository Dictionary, tells us that it is an ‘important word in the language of worship.’

Like the Psalmist, how can we Believers do anything else but praise our gracious and Holy God?  For He has done great things and is greatly to be praised.  In a great number of the 150 Psalms we find the Psalmist, David, speak of praising God.  I will share just a few verses here.

We praise the Lord:
In song:
“Sing praises to the LORD, who dwells in Zion!
 Declare His deeds among the people.”  Psalm 9:11

With musical instruments:
“Praise the LORD with the harp;
 Make melody to Him with an instrument of ten strings.”  Psalm 33:2

All are to praise Him:
“Let the people praise You, O God;
 Let all the people praise You.”  Psalm 67:3

Praise is to be on going:
“Therefore by Him (Christ) let us continually offer the sacrifice of praise to God, that is the fruit of our lips, giving thanks to His name.”  
Hebrews 13:12

And why?
“But you are a chosen generation, a royal priesthood, a holy nations, His own special people, that you  may proclaim the praises of Him who called you out of darkness into His marvelous light”  1Peter 2:9

Psalm 150 is the glorious song of praise and worship, it’s focus is wholly unto the Lord.

Praise is worship unto our Holy God from our whole heart!  And this not just at our Sunday worship, but moment by moment through our actions as well as our words.  How?  

In love:
“You shall love the LORD you God with all your heart, with all your soul, and with all your might.”  Deuteronomy 6:5

In obedience:
“Blessed are those who keep His testimonies,
 Who seek Him with the whole heart.”  Psalm 119:2

In trust:
“Trust in the LORD with all your heart,
 And lean not on your own understanding.”  Proverbs 3:5

In prayer:
“And you will seek me, and fine me, when you search for Me with all your heart.”  Jeremiah  29:13

In repentance:
“‘Now, therefore,’ says the LORD, 
‘Turn to Me with all your heart,
 With fasting, weeping and with mourning.’”  Joel 2:12
“For the sorrow that is according to the will of God produces a repentance without regret, leading to salvation…” 2 Corinthians 7:10

So with thanksgiving we sing to the only wise and awesome God:
“Praise God from whom all blessings flow,
 Praise Him all creatures here below.
 Praise Him above ye heavenly host.
 Praise Father, Son and Holy Ghost.”

I close with the doxology in Jude --
“Now unto Him who is able to keep you from falling (stumbling),
 And to present you faultless
 Before the presence of His glory with exceeding joy,
 To the only wise God our Savior,
 Be glory and majesty, dominion and power,
 Both now and forever,  Amen”  Jude 24-25
