Life here on earth is to be used as much as possible to establish the Kingdom of God on earth. Our eternal life begins as soon as we are born again as Jesus tell us in the Gospel of John chapter 3, and continues for eternity. I heard this quote when I was 22, (This life soon will pass only what’s done for Jesus will last).

For we know that when this earthly tent we live in is taken down (that is, when we die and leave this earthly body), we will have a house in heaven, an eternal body made for us by God himself and not by human hands. We grow weary in our present bodies, and we long to put on our heavenly bodies like new clothing. For we will put on heavenly bodies; we will not be spirits without bodies While we live in these earthly bodies, we groan and sigh, but it’s not that we want to die and get rid of these bodies that clothe us. Rather, we want to put on our new bodies so that these dying bodies will be swallowed up by life. 2 Corinthians 5:1-4
