The answer to burnout is spending time with God.

No matter how much material you read or how many seminars you attend on stress, you will find the relief you want from stress and burnout by going to God and letting God refresh your soul.

The Lord will give rest to the overburdened. In other words, the Lord will give rest to the burned-out!
Come to Me, all you who labor and are heavy-laden and overburdened, and I will cause you to rest. [I will ease and relieve and refresh your souls.]
(Matt. 11:28)

The Lord is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters. He restoreth my soul....
(Ps. 23:1-3 KJV)
The Lord's burden is to be light and easy to carry. We take His yoke upon us by obeying His promptings.
Take My yoke upon you and learn of Me, for I am gentle (meek) and humble (lowly) in heart, and you will find rest (relief and ease and refreshment and recreation and blessed quiet) for your souls.

For My yoke is wholesome (useful, good—not harsh, hard, sharp, or pressing, but comfortable, gracious, and pleasant), and My burden is light and easy to be borne.
(Matt. 11:29-30)
Enter into the Lord's rest by believing, trusting and relying on Him:
For we who have believed (adhered to and trusted in and relied on God) do enter that rest, in accordance with His declaration that those [who did not believe] should not enter when He said, As I swore in My wrath, They shall not enter My rest; and this He said although [His] works had been completed and prepared [and waiting for all who would believe] from the foundation of the world.
(Heb. 4:3)
Use Wisdom
Your body is the temple of the Holy Spirit.
Do you not know that your body is the temple (the very sanctuary) of the Holy Spirit Who lives within you, Whom you have received [as a Gift] from God?  You are not your own,

You were bought with a price[purchased with a preciousness and paid for, made His own]. So then, honor God and bring glory to Him in your body.
(1 Cor. 6:19-20)
The Lord gives power to the faint and weary; but remember, if you are worn out from continually exceeding your physical limitations, you need physical rest.

The Lord may mercifully give you supernatural energy in particular instances, but you are in disobedience when you abuse your body, the temple of the Holy Spirit. As we have seen, the anointing lifts when you operate outside of God's promptings.

If you want God to flow through and work through you, you need to take care of your body so that God can use you. If we wear out the body we have, we don't have a spare in a drawer somewhere to pull out!
