The first item of question and answer in the Westminster Shorter Catechism,is:
Q. What is the chief purpose for which man is made?
A. The chief purpose for which man is made is to glorify God, and to enjoy Him forever.
We glorify God when we be the person whom God created us to be, and do the things that He gifted us to do, for Him.
An eagle hovers upon the thermal updraft and we stand in awe of her wonder and beauty, as she glorifies the God who made her.
A singer sings and touches our hearts deeply, and we are in awe of their God given talents etc etc.
The second part of that answer is: To Enjoy Him Forever.
To enjoy God is a great privilege of his grace towards us. To enjoy someone requires a relationship and it requires communication and conversation - that is what prayer is - talking to God and getting to know him better with the help of his love letter to us, the bible.
I talk much more with the Lord now that I am alone, (than when my life had all its i's dotted and t's crossed) and He provides to me strength, comfort and joy - even amidst great difficulties. Prayer is the lifeblood of a christians relationship with God, just as conversation is in the relationship between a man and a woman.
When I dress up in the most ridiculous of costumes and walk or dance in the streets - I feel His pleasure upon me. Why? because that is what He gifted me to do. I know that Jesus has a sense of humour - to have created such a motley man as I, (and quite a few of you as well) - He must have one. Therefore, I walk and dance for Him.
"Don't you fear God?"
One Thief loathed Him and One Thief chose Him,
One thief affirmed Him as innocent and one thief affirmed himself.
One showed his fear of God and one showed his contempt for God.
One man defended the innocent and one man sided with the mob.
One sinner laughed at Him and one sinner longed for Him.
One sinner confessed to Him and one sinner condemned Him.
One soul assailed Him and One soul accepted Him.
One Thief entered heaven to be with Him forever.
The soldiers also came up and mocked him. They offered him wine vinegar and said,
“If you are the king of the Jews, save yourself.”
There was a written notice above him, which read: "This is the king of the Jews".
One of the criminals who hung there hurled insults at him: “Aren’t you the Messiah? Save yourself and us!”
But the other criminal rebuked him. “Don’t you fear God,” he said, “since you are under the same sentence? We are punished justly, for we are getting what our deeds deserve. But this man has done nothing wrong.”
Then he said, “Jesus, remember me when you come into your kingdom.”
Jesus answered him, “Truly I tell you, today you will be with me in paradise.”
Luke 23:36-43 (NIV)
