Praise in general terms is to commend, applaud, approve, admire or glorify an object or a person. For the Christian, praise to God is an expression of worship wherein we humble ourselves and centre our attention upon the Lord, offering genuine praise, adoration and thanksgiving to God.
Many Christians today are so involved in many other activities and they have lost their focus on God. Most Christians major on getting from God and dealing with the enemy. This is because such Christians have not grasped the fact that praise itself is a powerful weapon against the enemy. Let the instrument of praise be one of your key weapons in warfare. In 2 Chronicles 20:21-23, Jehoshaphat King of Judah sent his army led by praise singers against the Ammonites, Moabites and they of Mount Seir. The bible records in verse 22 that when they began to sing and to praise, the Lord set ambushments against their enemies: they were not only smitten but they also destroyed each other. Judah had no need to fight at all; all they did was gather the spoil, which was in such abundance that it took about 3 days to gather.
Praise brings down the presence and glory of God, and when the presence of God comes down, his deliverance will follow. (2 Chron 5:13-14) When you praise God, you invoke a manifestation of the glory and power of God.
Praising God makes us humble; it puts the focus on God and away from your problems. The most important thing you can do in any situation is praise God. Praise will increase your faith and bring answers to prayers more quickly.
The most important reason to praise God however is because it ministers to God. God inhabits the praise of his people. God made us for his pleasure. God created us to give him praise. (Rev 4:11) All of creation is for the sole purpose of praising God and giving honour and glory to his name. In essence, anything else you find yourself doing now is a part time job or engagement.
