As a person, you have a destiny. There is only one way to fulfill your destiny.

Many people try to be fulfilled by using all types of systems and ideas that could never have the potential for their fulfillment. You were created to be fulfilled, and pleasure, possessions, power, success, friendships, and such things, good as they are, could never make you fulfilled. You were created to be fulfilled in only one way. That is why you feel unfulfilled.

Jesus prayed in John 17:13 And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.

God is concerned that we are fulfilled. It all has to do with coming into unity with God.

John 17:21-25 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me. Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world. O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.

It has to do with life, that is, knowing God.

John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.

It has to do with power, as these Scriptures point out:

Luke 24:49 And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.

Act 1:4-8 And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said to them, It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses to me both in Jerusalem, and in all Judea, and in Samaria, and to the uttermost part of the earth.

It has to do with the redemption of your body:

Romans 8:19-23 For the earnest expectation of the creature waiteth for the manifestation of the sons of God. For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope, Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groaneth and travaileth in pain together until now. And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.

Psalm 17:15 As for me, I will behold thy face in righteousness: I shall be satisfied, when I awake, with thy likeness.

Until all of these things are fulfilled in your life, you can have a measure of fulfillment by walking in the Spirit. If you do, you will go from glory to glory and from faith to ever deeper faith.

2 Corinthians 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.

Romans 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
