Revelation 4:11 ESV "Worthy are you, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created."
Why should we thank God and praise God?
1. He told us to do it: (rejoice, praise, exalt His name, and worship the Lord): (Romans 15:9-11)
Romans 15:9-11 ESV and in order that the Gentiles might glorify God for his mercy. As it is written, "Therefore I will praise you among the Gentiles, and sing to your name." (10) And again it is said, "Rejoice, O Gentiles, with his people." (11) And again, "Praise the Lord, all you Gentiles, and let all the peoples extol him."
2. He is God and He is worthy. Our creator, sustainer, made the heavens and earth, gives us our every breath, and every good gift.
3. Praise is an acceptable sacrifice to Him. If done properly with right attitude. I can give to the Creator praise, worship and honor because of our Lord Jesus Christ and the Person of the Holy Spirit:
Hebrews 13:15-16 ESV Through him then let us continually offer up a sacrifice of praise to God, that is, the fruit of lips that acknowledge his name. (16) Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God.
Revelation 8:3-4 ESV And another angel came and stood at the altar with a golden censer, and he was given much incense to offer with the prayers of all the saints on the golden altar before the throne, (4) and the smoke of the incense, with the prayers of the saints, rose before God from the hand of the angel.
(1 Peter 2:5 ESV) you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.
(1 Peter 2:6 ESV) For it stands in Scripture: "Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame."
(1 Peter 2:7 ESV) So the honor is for you who believe, but for those who do not believe, "The stone that the builders rejected has become the cornerstone,"
(1 Peter 2:8 ESV) and "A stone of stumbling, and a rock of offense." They stumble because they disobey the word, as they were destined to do.
(1 Peter 2:9 ESV) But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.
(Psalms 27:6 ESV) And now my head shall be lifted up above my enemies all around me, and I will offer in his tent sacrifices with shouts of joy; I will sing and make melody to the LORD.
