One Hebrew word for “praise” is yadah, meaning “praise, give thanks, or confess.”
A second word often translated “praise” in the Old Testament is zamar, “sing praise.”
A third word translated “praise” is halal (the root of hallelujah), meaning “to praise, honor, or commend.”
All three terms contain the idea of giving thanks and honor to one who is worthy of praise.
Praise, according to the Scriptures, is an act of our will that flows out of an awe and reverence for our Creator. Praise gives glory to God and opens us up to a deeper union with Him. It turns our attention off of our problems and on the nature and character of God Himself.
As we focus our minds on God and proclaim His goodness, we reflect His glory back to Him. The results can fill you with peace and contentment ( Isaiah 26:3) and transform your outlook on life.
 praising God 1
Praising God is a God-appointed calling. Indeed, God has formed for himself a people “that they may proclaim my [God’s] praise” (Is. 43:21, Jer. 13:11). God’s actions, such as Israel’s restoration from the exile, are to result in God’s “righteousness and praise spring [ing] up before all nations” (Is. 61:11). God has also predestined the church “to the praise of his [God’s] glorious grace” Eph. 1:6, Matt. 5:16, Eph. 1:14, Phil.1:11, 1Pet. 2:9). The future vocation of the redeemed in glory is to sing praise to God and the Lamb (Rev. 4:11, 5:12-14, 7:12).
No matter how we praise God, we must be sure to lift up His name above all else. “For the Lord is great and greatly to be praised; He is to be feared above all gods” (Ps. 96:4). Putting other people or things before God is easy to do, but with the Holy Spirit’s help, let us praise God with all of our might.
Living a life of praise is not only the most enjoyable way to live, but it’s also one of the most powerful ways to change your life. Praise isn’t like the caboose that just follows what happens, but it’s more like the engine of a train that makes things happen. Your faith isn’t complete without praise. Colossians 2:7 says that you abound in faith with thanksgiving. No thanksgiving equals not abounding in faith.
Praise affects you, it affects the devil, and it affects God. It touches everything and every part of your life. Likewise, a lack of praise affects you in a negative way, turns the devil loose in your life, and doesn’t bless God. You have to get this area of your life right.
In all of these instances, praising God is simply giving Him the recognition He deserves. One way we can define what we mean by praising God is to consider the end result.
The end result of giving God praise is to exalt Him and His name. I believe this is one of the reasons the psalmist quickly followed the declaration of praise with exalting God.
We can praise God in song, and singing praises to God was common even back in biblical times. The main purpose of the Psalms is to praise God—indicated by the numerous songs on praise.
We can also praise God in dance, prayer, proclamations, studying God’s Word, and the list goes on.
