So when our Sun "dies" how will future humans surv

As a Christian, whenever the topic of the end of the world comes up, we are told that that is not true. Evangelists say that this world will never end, that Jesus will return someday etc.. Yet eventually this world will end because of our sun. I'm curious as to how this fits into Christianity. Eventually life will not be able to live on Earth any longer. So what happens to future humans?
"The Sun's Future
As the Sun slowly runs out of hydrogen fuel, it will gradually start growing hotter with time as the core contracts and heats up due to the increased pressure. It is estimated that in about 1 billion years, most complex life will not be able to survive on Earth due to the heating.
Artist's conception of the remains of artificial structures on the Earth after the Sun enters its red giant phase and swells to roughly 100 times its current size.Eventually the Sun will end its primary life in a violent explosion. The Sun does not have enough mass to explode as a supernova. Instead, in 4—5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed. Helium fusion will begin when the core temperature reaches about 3×108 K. While it is likely that the expansion of the outer layers of the Sun will reach the current position of Earth's orbit, recent research suggests that mass lost from the Sun earlier in its red giant phase will cause the Earth's orbit to move further out, preventing it from being engulfed. However, Earth's water and most of the atmosphere will be boiled away.
Following the red giant phase, intense thermal pulsations will cause the Sun to throw off its outer layers, forming a planetary nebula. The Sun will then evolve into a white dwarf, slowly cooling over eons. This stellar evolution scenario is typical of low- to medium-mass stars."
