Philippians 1:21-24 ESV
For to me to live is Christ, and to die is gain. If I am to live in the flesh, that means fruitful labor for me. Yet which I shall choose I cannot tell. I am hard pressed between the two. My desire is to depart and be with Christ, for that is far better. But to remain in the flesh is more necessary on your account.
A Christian ought not to fear death. To die is to depart from the flesh and be with Christ in heaven, which is far better. No more temptation, pain and suffering of the flesh. However, to remain in the flesh and in this world means we can do fruitful labour for Christ. It's necessary for the work of the Church & helping others.
As a result, we must keep in mind that the purpose God let us stay in this world is for building our character, preaching the Gospel, helping others, and serving the Church. We can relax and enjoy eternally when we are with Christ in heaven. For now, just for a short while, we are here in this world to do fruitful labour for the cause of Christ. So minimize our enjoyment and focus on our work
