There are purposes for which God created us all. As well, God has given each of us talents and gifts which equip us for specific works or tasks.

“For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.” Ephesians 2:10
When we surrender our lives to Jesus Christ, our Heavenly Father sends the Holy Spirit to guide us to accomplish those works as long as we obey His commands – “not my will, but yours, be done” Luke 22:42.
To Glorify God
Everything was created for a purpose…including us. The Bible is clear about one of our purposes, and that is that we are to glorify God. For example, if we get into trouble, we are told to:
“call upon me in the day of trouble; I will deliver you, and you shall glorify me” Psalm 50:15.
The psalmist knew that it was:
“Not to us, O Lord, not to us, but to your name give glory, for the sake of your steadfast love and your faithfulness. Psalm 115:1.
Answered prayer gives God glory, so the Lord our God is to be praised and we should seek to glorify His name. We certainly have nothing to boast or brag about. The Lord says,
“I am the LORD; that is my name; my glory I give to no other, nor my praise to carved idols.” Isaiah 42:8
If you look at the creation, you can see for yourself that
“The heavens declare the glory of God, and the sky above proclaims his handiwork.” Psalm 19:1
So rightfully we should say:
“O LORD, our Lord, how majestic is your name in all the earth! You have set your glory above the heavens.” Psalm 8:1
The first purpose for which we were created was to give God glory and make His glory known to others.
To Make Disciples
When Jesus gave the Great Commission, which in essence is an imperative command, He didn’t give them a second option or Plan B. He said, “All authority in heaven and on earth has been given to me” (Matthew 28:18b), and since God has given Jesus all authority in heaven and on earth, He is passing this authority on to them, which is why He can say,
“Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” Matthew 28:19.
That doesn’t mean everyone that they share Christ with will become disciples of Christ. They are only told to go and make disciples, but it is generally understood that God will use them as a means to make disciples (Acts 2:47), and He did. He sent them into different parts of the world to bring the gospel since they had God’s authority, but the Commission is not quite finished yet. Jesus commands them.
“teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” Matthew 28:20
So how does making disciples glorify God? The more there are to worship and praise God in the kingdom, the more glory He will receive. In a prophetic Scripture, the psalmist writes, “All the nations you have made shall come and worship before you, O Lord, and shall glorify your name” (Psalm 86:9). In the kingdom, “they [will] sing the song of Moses, the servant of God, and the song of the Lamb” (Rev. 15:3a), asking, “Who will not fear, O Lord, and glorify your name? For you alone are holy. All nations will come and worship you, for your righteous acts have been revealed” (Rev. 15:4). That is one of our purposes. It is to bring as many to Christ as the Lord our God will save, knowing that He alone saves (Acts 4:12), but He is still pleased to use us as a means to save some.
Works for His Glory
God has prepared works for us to do after we are saved. The only question is, Will we walk in them? Jesus told His disciples,
“If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you. By this, my Father is glorified, that you bear much fruit and so prove to be my disciples.” John 15:7-8
Fruit never glorifies us but it always glorifies God, because we can do nothing without Christ (John 15:5). We must remain in Him or abide or dwell in the Vine (Christ) or we will only bear wax fruit, and not genuine fruits of the Spirit, but we will also begin to bear good works as a by-product of our salvation, but even this is from the Spirit of God, therefore, all works we do give God glory. There is no good we can do in our own human strength (Isaiah 64:6).
