Why did God make you? Why did He bring you into existence? It wasn't so you could just live as you like. No, God made you for His purposes, to fulfill His will in the world.
What is God's will for you?
That you would know Him.
John 17:3
3 "This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
Philippians 3:7-10
7 But whatever things were gain to me, those things I have counted as loss for the sake of Christ.
8 More than that, I count all things to be loss in view of the surpassing value of knowing Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them but rubbish so that I may gain Christ,
9 and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith,
10 that I may know Him...
Ephesians 1:15-19
15 Wherefore I also, after I heard of your faith in the Lord Jesus, and love unto all the saints,
16 Cease not to give thanks for you, making mention of you in my prayers;
17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:
18 The eyes of your understanding being enlightened; that you may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,
19 And what is the exceeding greatness of his power to us-ward who believe...
That by knowing Him, you would come to love Him.
1 John 4:16-19
16 And we have known and believed the love that God has for us. God is love; and he who dwells in love dwells in God, and God in him.
17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
18 There is no fear in love; but perfect love casts out fear: because fear has torment. He who fears is not made perfect in love.
19 We love him, because he first loved us.
Matthew 22:35-38 (NASB)
35 One of them, a lawyer, asked Him a question, testing Him,
36 "Teacher, which is the great commandment in the Law?"
37 And He said to him, " 'YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND.'
38 "This is the great and foremost commandment.
That in loving Him, you would enjoy Him.
That in enjoying Him, you would glorify Him.
1 Corinthians 8:3 (NASB)
3 but if anyone loves God, he is known by Him.
That in loving God, you would enjoy Him.
Psalm 16:11
11 You will make known to me the path of life; In Your presence is fullness of joy; In Your right hand there are pleasures forever.
John 15:11
11 "These things I have spoken to you so that My joy may be in you, and that your joy may be made full.
Acts 13:52
52 And the disciples were continually filled with joy and with the Holy Spirit.
Romans 14:17
17 for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.
That in enjoying God, you would glorify Him.
1 Corinthians 10:31
31 Whether, then, you eat or drink or whatever you do, do all to the glory of God.
1 Corinthians 6:20
20 For you have been bought with a price: therefore glorify God in your body.
Romans 15:5-6 (NASB)
5 Now may the God who gives perseverance and encouragement grant you to be of the same mind with one another according to Christ Jesus,
6 so that with one accord you may with one voice glorify the God and Father of our Lord Jesus Christ.
This is why you (and everyone else) exist. So, do you know God? Do you love Him? Are you enjoying Him? Out of your enjoyment of God are you glorifying Him?
You see, God thinks that He is the very best thing that He can give to us. But, we think many other things are more important, more valuable, more satisfying. And so, although we trust in Christ as our Savior and Lord, and the Holy Spirit comes to live within us, we aren't satisfied. Even though the Greatest Thing in the entire universe is ours - God Almighty - we want more: health, wealth, comfort, physical pleasure.
What God is wanting to teach us is that He really is more awesome than anything else we can have or experience. And when, in our minds and hearts, we know Him to be so, we can be content no matter what situation we're in. When we see God as He is, and experience His fullness in our living every day, we can be sick, and isolated, and destitute and still be joyful and content. And so, often when we pray for better health, or more money, or happier circumstances, God doesn't answer because all of these things get in the way of us seeing God clearly and enjoying Him fully. God's priority for us is that we know Him because in Him we find all we were made for and a foundation for joyful living that cannot be shaken by anything.
Genesis 15:1
1 After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am your shield, and your exceeding great reward.
