If you lead with observation, you take in more than you give out, and you protect your time and energy carefully because they feel finite. Scripture has a long conversation between God and a man making exactly that argument, and the answer is not what you'd expect from either side.
He Was Arguing About Supply
Moses is at the burning bush and has run out of objections except this one.
"Pardon your servant, Lord. I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue" (Exodus 4:10).
Read what kind of objection that is. He isn't disputing that Israel should be rescued and he isn't questioning God's power to do it. He's saying he does not personally have what the job requires. It's an inventory problem.
God's answer goes straight past the inventory. "Who gave human beings their mouths? Who makes them deaf or mute? Who gives them sight or makes them blind? Is it not I, the Lord? Now go; I will help you speak and will teach you what to say" (Exodus 4:11-12).
Moses tries once more, and it's the most honest line in the exchange: "Pardon your servant, Lord. Please send someone else" (Exodus 4:13).
Then something worth noticing. God's anger burns, and what he does with it is provide Aaron. "You shall speak to him and put words in his mouth; I will help both of you speak and will teach you what to do" (Exodus 4:15). The assignment does not get withdrawn and Moses does not get left to do it out of his own reserves.
The Reserve You're Protecting
So the argument you're most likely to make is the one Moses made. Not that God is wrong, but that you personally do not have enough to give, and that you'd rather withdraw and prepare than step into something that will drain you.
That instinct is not irrational. You do run out faster in crowded rooms, and the recovery is real. What's worth testing is the belief underneath it, which is that what you have is a fixed amount that only ever decreases.
Moses' supply was never the operative fact. God supplied the words as they were needed, and sent a person to work alongside him. The provision arrived in the doing, not before it, which is inconvenient if you'd prefer to be adequately resourced before you begin.
So try one thing that you have not fully prepared for. Say yes before you feel ready and watch what shows up while you're doing it.
Knowing About God and Knowing God
Here is the specific trap for you and it will look exactly like devotion.
You can build a serious understanding of scripture. Commentaries, original words, the historical context of a passage. All of that is worth having, and the church benefits from people who have it. It can also be a way of standing at a distance from God while appearing to draw near.
The test is simple. When did you last say something to God that you hadn't worked out first?
Try praying badly on purpose. No structure, no preparation, no interesting theological framing. Tell him what's actually happening in your life and don't tidy it up. Understanding is not the same as being with somebody, and you already know that about people.
People Are Not Only a Cost
The other thing to name is what happens to your relationships when energy feels scarce.
You'll manage people the way you'd manage a budget: keep visits short, avoid the situation that might turn into a long conversation, be unavailable in advance. Over years that produces a life with very few people in it and a set of reasons that all sound sensible one at a time.
Notice that God's provision to Moses was a person. Not more words, not a better skillset. His brother, walking toward him already.
Pick one relationship and be available in it without a plan for getting out. That will cost you more than the reading does, and it's where the growth is.
Who Else Held Back First
No one in scripture was ever typed. Plenty of them argued that they had too little to give.
Moses argues about his own mouth and is given Aaron. Gideon says his clan is the weakest and he is the least in his family. Jeremiah says he is too young. The boy with five loaves hands over a lunch that couldn't feed a crowd. Every one of them was right about their own supply, and it was the wrong measurement.
Three Things to Try
Three things this month. Say yes to something before you feel prepared, and watch what arrives while you're doing it. Pray once without composing it first. Be available to one person with no exit planned. And the Head center sets 5, 6, and 7 alongside each other, which is useful because all three are managing fear and only one of them looks anxious.
Moses asked God to send somebody else. God sent Aaron with him and kept Moses on the job.
