God does not need praise. There is no lack in him. There is no "need" that God has which must be satisfied. If there were, it would mean that God was insufficient in and of himself. Instead, God is the perfect one, the holy one, above whom is no other God (Isaiah 43:10; 44:6, 8; 45:5). He alone is worthy of adoration. He is our Creator, and he became one of us in Christ Jesus (John 1:1, 14), and died for our sins (1 Cor. 15:1-4; 1 Pet. 2:24). God, therefore, is naturally worthy of praise because of his perfect and holy nature. So, praising God is the right thing to do.
Furthermore, we praise him because of how wonderful he is. He is glorious (Psalm 21:4), good (Psalm 107:1), created all things (Rev. 4:11), blesses his people (Deut. 12:7), and hears our prayers (Psalm 116:2). Praise is the mark of the Christian (Phil. 1:11; 1 Pet. 2:9).
Praise is related to who you are praising and why you are praising. Consider this. Our sin separates us from God (Isaiah 59:2). Sin is breaking the law of God (first John 3:4). Sin has consequences just as breaking any law has consequences. The only way to be saved from the righteous judgment of God is through the work of Christ. He lived a perfect life without ever sinning (1 Peter 2:22). He also bore our sins in his body and the cross (1 Peter 2:24). Since there's nothing we can do by which we might earn the forgiveness of God (Rom. 3:28; Gal. 2:21), then the only thing we can do is trust in the work of Christ on the cross. This is why the Bible tells us that we are "justified by faith," (Rom. 5:1). The reason this is so important is because faith is only as good as so you put it in. Therefore, when we praise God, we are praising the holy one in whom we believe.
So, praising God is actually a form of faithful adoration to the true and living God that is only make possible through the cross of Christ. Praising God as part of having faith. Therefore, it's good to praise God because in it we are having faith in him and, ultimately, his work on the cross.
Also, praising God is good for the one who praises him. There is something spiritually beneficial when we humble ourselves and praise him. There's a spiritual benefit to worshiping him, to speak of him in terms of adoration. Somehow, someway God is there with us in our praises to him. As a result, we grow in our relationship with him and obtain a better understanding of who he is. Praise is an experience of adoration, not just an intellectual undertaking. Therefore, praise involves our hearts more than our minds.
