It’s all for him.
The ultimate goal of the universe is to show the glory of God. It is the reason for everything that exists, including you. God made it all for his glory. Without God’s glory, there would be nothing.
What is the glory of God? It is who God is. It is the essence of his nature, the weight of his importance, the radiance of his splendor, the demonstration of his power, and the atmosphere of his presence. God’s glory is the expression of his goodness and all his other intrinsic, eternal qualities.
Where is the glory of God? Just look around. Everything created by God reflects his glory in some way. In nature we learn that God is powerful, that he enjoys variety, loves beauty, is organized, and is wise and creative. The Bible says, “The heavens declare the glory of God.” 
God’s inherent glory is what he possesses because he is God. It is his nature. We cannot add anything to this glory, just as it would be impossible for us to make the sun shine brighter. But we are commanded to recognize his glory, honor his glory, declare his glory, praise his glory, reflect his glory, and live for his glory.  Why? Because God deserves it! We owe him every honor we can possibly give. Since God made all things, he deserves all the glory. The Bible says, “You are worthy, O Lord our God, to receive glory and honor and power. For you created everything.”
How can I Bring Glory to God?
We bring God glory by worshipping him. Worship is our first responsibility to God. We worship God by enjoying him. C.S. Lewis said, “In commanding us to glorify him, God is inviting us to enjoy him.” God wants our worship to be motivated by love, thanksgiving, and delight, not duty.
Worship is far more than praising, singing, and praying to God. Worship is a lifestyle of enjoying God, loving him, and giving ourselves to be used for his purposes. When you use your life for God’s glory, everything you do can become an act of worship.
We bring God glory by loving other believers. When you were born again, you became a part of God’s family. Following Christ is not just a matter of believing; it also includes belonging to and learning to love the family of God.
It is your responsibility to learn how to love as God does, because God is love, and it honors him. “As I have loved you, so you must love one another. By this all men will know that you are my disciples, if you love one another.” 
We bring God glory by becoming like Christ. Once we are born into God’s family, he wants us to grow to spiritual maturity. What does that look like? Spiritual maturity is becoming like Jesus in the way we think, feel, and act. The more you develop Christlike character, the more you will bring glory to God. The Bible says, “As the Spirit of the Lord works within us, we become more and more like him and reflect his glory even more.” 
We bring God glory by serving others with our gifts. Each of us was uniquely designed by God with talents, gifts, skills, and abilities. The way you’re “wired” is not an accident. God didn’t give you your abilities for selfish purposes. They were given to benefit others, just as others were given abilities for your benefit. The Bible says, “God has given gifts to each of you from his great variety of spiritual gifts. Manage them well so that God’s generosity can flow through you….Are you called to help others? Do it with all the strength and energy that God supplies. Then God will be given glory.” 
We bring God glory by telling others about him. God doesn’t want his love and purposes kept a secret. Once we know the truth, he expects us to share it with others. This is a great privilege — introducing others to Jesus, helping them discover their purpose, and preparing them for their eternal destiny.
What will you live for?
Living the rest of your life for the glory of God will require a change in your priorities, your schedule, your relationships, and everything else. It will sometimes mean choosing a difficult path instead of an easy one.
Right now, God is inviting you to live for his glory by fulfilling the purposes he made you for. It’s really the only way to live. Everything else is just existing.
