Time and space all belong to God. With God, time does not exist, for he is eternal. For us, you might say that we exist on earth briefly on borrowed time from God and if we remain obedient to him, we become eternal too after our earthly life ends. Basically, we do not own anything, but can be owned by God as his beloved sons and daughters. Then if we rebel against God, we get ourselves disowned by him in the end. It's all pretty straight forward.
