The everlasting God . . . neither faints nor is weary —Isaiah 40:28
Exhaustion means that our vital energies are completely worn out and spent. Spiritual exhaustion is never the result of sin, but of service. Whether or not you experience exhaustion will depend on where you get your supplies. Jesus said to Peter, “Feed My sheep,” but He gave him nothing with which to feed them (John 21:17). The process of being made broken bread and poured-out wine means that you have to be the nourishment for other people’s souls until they learn to feed on God. They must drain you completely— to the very last drop. But be careful to replenish your supply, or you will quickly be utterly exhausted. Until others learn to draw on the life of the Lord Jesus directly, they will have to draw on His life through you. You must literally be their source of supply, until they learn to take their nourishment from God. We owe it to God to be our best for His lambs and sheep, as well as for Him.
Have you delivered yourself over to exhaustion because of the way you have been serving God? If so, then renew and rekindle your desires and affections. Examine your reasons for service. Is your source based on your own understanding or is it grounded on the redemption of Jesus Christ? Continually look back to the foundation of your love and affection and remember where your Source of power lies. You have no right to complain, “O Lord, I am so exhausted.” He saved and sanctified you to exhaust you. Be exhausted for God, but remember that He is your supply. “All my springs are in you” (Psalm 87:7).
