Being exhausted for eternity is so fulfilling.
Your goal is never to get as tired as you can while serving the Lord, but the reality is that you will get tired in doing God’s work and will! Yes, you have rest in your heart from Jesus, but you are to keep your hand to the plow and serve the Lord full-heartedly— never half-heartedly. Give your all for the sake of the kingdom and continue to reach out to lost souls and hurting people. You can be both tired and fulfilled from doing the Lord’s work. Make sure you do get physical rest, but always giving your all unto the Lord.
