Retire from the things of God? Ending in the best way.

God calls us to serve, we know when it begins but not when it ends, it has no end.
6 For I am already ready to be sacrificed, and the time of my departure is at hand. 7 I have fought the good fight, I have finished the race, I have kept the faith. 8 Finally, there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me on that day; and not to me only but also to all who love his appearing.
2 Timothy 4:6-8
There are many people who, while working throughout their lives, think about that day when they will retire, they believe that they will only dedicate themselves to leisure, it is something similar to the work of God, some think that at some point in their life they will stop serving and will only dedicate themselves to leisure. But this is not what God has planned for us. God wants us to serve until the last of our days!
In the Bible we have many examples and one of them is the apostle Paul, he is an example of dedication and service to other people. For this we can simply look at the letter written to Timothy, just before Paul is executed, this is another example of service even when we believe that that moment is over, God calls us to service constantly.
Paul is an example of dedication and service until the end of his life. Through his writings we can understand his mind regarding this:
12 Therefore, brothers, I urge you, by the mercies of God, to present your bodies a living sacrifice, holy, pleasing to God, which is your spiritual worship.
Romans 12:1
