When you die.. is it because that is when God chose for you to die, and everything goes according to his plan.. or you just happened to die at that time and God just let it happen and didn't stop it.
For that matter, do we have a purpose we have to fulfill? And based on the above answer, if so, do we only die after that purpose is fulfilled or are we just here cause we are and should make the best of it and do good things for others. (I'm not talking about accepting Christ, I know you have to do that)
Thanks in advance for your opinions. Bible verses also would be helpful.
Yes, all believers have a purpose to fulfill. Although we can see the power of God's love by sending His own Son to die for our sins (John 3:16), God did not intend for us to stay as saved sinners.
First of all, God saved us because He intends for us to do good works. Otherwise, God would have never prepared good works for us to do before we were even saved.
Ephesians 2:10 "For we are His workmanship, created in Christ Jesus
for good works, which God prepared beforehand that we should walk in them."
Secondly, God intends for us to share the gospel.
Matthew 28:18-20 "All authority has been given to Me in heaven and on earth. Go therefore, and make disciples of all the nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all things that I have commanded you. And lo, I am with you always even to the end of the age."
Lastly, our faith in Jesus should naturally produce good works. I am not saying that good works are necessary for salvation. I am saying that a saved person should naturally produce good works, just as a married man naturally produces good works towards his wife.
James 2:18-20 "18 But someone will say, “You have faith, and I have works.” 
wShow me your faith without 
6your works, 
xand I will show you my faith by 
7my works. 19 You believe that there is one God. You do well. Even the demons believe—and tremble! 20 But do you want to know, O foolish man, that faith without works is 
8dead?"
