Praise and Thanksgiving
The Lord's Prayer begins and ends with praise. Giving praise to God helps us to understand just how awesome He really is! We should praise Him for how powerful He is. We should praise Him for how giving He is. We should praise Him for how loving He is. We should thank Him for all that He has done, is doing and will do for us as His children. And the list goes on …

In the New Testament Paul tells of giving thanks to God:

"We always thank God, the Father of our Lord Jesus Christ, when we pray for you, … and joyfully giving thanks to the Father, who has qualified you to share in the inheritance of the saints in the kingdom of light. For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves, in whom we have redemption, the forgiveness of sins." - Colossians 1:3,12-14

"For this reason, ever since I heard about your faith in the Lord Jesus and your love for all the saints, I have not stopped giving thanks for you, remembering you in my prayers." - Ephesians 1:15-16

"Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God." - 2 Corinthians 1:3-4

We are actually commanded to give praise and thanksgiving to God:

"Through Jesus, therefore, let us continually offer to God a sacrifice of praise - the fruit of lips that confess his name. And do not forget to do good and to share with others, for with such sacrifices God is pleased." - Hebrews 13:15-16

"Be joyful always; pray continually; give thanks in all circumstances, for this is God's will for you in Christ Jesus." - I Thessalonians 5:16-18

"Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, for our 'God is a consuming fire.'" - Hebrews 12:28-29

"Rejoice in the Lord always. I will say it again: Rejoice! Let your gentleness be evident to all. The Lord is near. Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." - Philippians 3:15

In the Old Testament one can find passage after passage of praises to God; especially in the book of Psalms which is packed with chapters on the praise of God and His power and glory. Here are two examples:

"O Lord, our Lord, how majestic is your name in all the earth! You have set your glory above the heavens. From the lips of children and infants you have ordained praise because of your enemies, to silence the foe and the avenger. When I consider your heavens, the work of your fingers, the moon and the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him? You made him a little lower than the heavenly beings and crowned him with glory and honor. You made him ruler over the works of your hands; you put everything under his feet: All flocks and herds, and the beasts of the field, the birds of the air, and the fish of the sea, all that swim the paths of the seas. O Lord, our Lord, how majestic is your name in all the earth!" - Psalm 8

"Clap your hands, all you nations; shout to God with cries of joy. How awesome is the Lord Most High, the great King over all the earth! He subdued nations under us, peoples under our feet. He chose our inheritance for us, the pride of Jacob, whom he loved. God has ascended amid shouts of joy, the Lord amid the sounding of trumpets. Sing praises to God, sing praises; sing praises to our King, sing praises. For God is the King of all the earth; sing to him a psalm of praise. God reigns over the nations; God is seated on his holy throne. The nobles of the nations assemble as the people of the God of Abraham, for the kings of the earth belong to God; he is greatly exalted." - Psalm 47
