The term "depleted" refers to the use of all supplies or resources. For something to become depleted, there must first be a supply to draw from.
 
Many people, however, live without any margin—defined as the space or buffer surrounding something. This lack of margin means we operate with minimal resources to begin with.
 
Consequently, when we encounter challenges, we quickly find ourselves depleted. This creates a cycle: feeling depleted prevents us from taking the necessary time to recharge, leading us deeper into a downward spiral.
 
Even positive things can deplete us when pursued without margins. We can exhaust ourselves mentally, spiritually, physically, and emotionally if we fail to establish boundaries and create space in our lives.
 
For instance, work is good; we are encouraged to approach it as if we are doing it for the Lord. However, when work begins to encroach on our time with God or interferes with our relationships with our spouse and children, or when we neglect our physical health, we set ourselves up for burnout.

John 16:33 points Jesus’ awareness of the challenges we would face in this world, even as Christians.  And his response was to fix our eyes on Him and trust that He is greater:

“I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world.”

Pray that God would help you assess the source of your depletion and unburden you as you trust him to sustain you even in the hardest seasons.
