Genesis 15:11, 12

And when the fowls came down upon the carcases, Abram drove them away.
And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him.

Abram has the pieces laid out before the Lord, and now he waits. But as he waits, the birds come down upon the sacrifice, and Abram has to drive them away. Throughout Scripture, birds often carry a dark association, and that seems to be the picture here. As Abram waits for God to move, he finds himself doing what every believer knows something about. He is fighting off the intrusions. He is trying to keep doubt back. He is pushing away unbelief. He is resisting the darkness that wants to settle down on the very place where he is waiting on God.

That feels familiar.

Because whenever a man begins to wait on the Lord, whenever he begins to stand on the promises of God, it is amazing how quickly the birds seem to show up. Doubts start circling. Fears start dropping in. Unbelief starts picking at the sacrifice. Questions start landing where faith had been resting just a few moments before.

So Abram does what he can. He drives them away.

And there is something admirable in that. There is a place for resisting unbelief. There is a place for saying, “No, I will not let that thought stay here. No, I will not give myself over to despair. No, I will keep waiting on the Lord.” Abram is not careless here. He is engaged. He is contending.

But eventually evening comes.

The sun starts going down. Abram grows weary. And then a deep sleep falls on him, along with a horror of great darkness. He had done his best to keep the evil at bay, but now his strength is gone. Now he is exhausted. Now he can do no more.

And that is where this scene gets very tender.

Because the Lord is about to show Abram that the covenant was never going to be secured by Abram’s striving. Abram had a part to play in preparing the pieces and driving away the birds, but the covenant itself would not rest on Abram’s ability to stay awake, stay strong, or stay vigilant. It was going to rest on God alone.

That is a lesson we all need.

Because there are seasons when we do our best to keep the birds away. We pray. We quote Scripture. We fight fear. We resist doubt. And yet there comes a point when we realize we cannot hold ourselves together by our own effort. We get tired. We get empty. We feel the darkness pressing in.

And in that moment, the good news is this. God does not need my strength in order to keep His promise.

Abram falls asleep.

In other words, the man who asked for assurance is brought to the end of himself. He can no longer contribute. He can no longer manage the scene. He can no longer guard the sacrifice. He is simply there, helpless, covered in darkness, waiting for God.

That is often where the Lord does His deepest work.

Not when I am strong and sharp and full of energy, but when I have come to the end of my own effort. Not when I think I can hold the whole thing together, but when I finally realize that if God does not do it, it will not be done.

Beloved, there is grace in that kind of exhaustion.

Because when my strength runs out, His faithfulness does not. When I cannot keep the birds away anymore, He is still God. When darkness settles heavy on my heart, His covenant is still sure. The promise does not hang on my ability to fight forever. It hangs on His ability to remain faithful always.

So yes, there is a time to drive the birds away.

But there is also a time when the Lord lets me see that even my best efforts were never the foundation of the covenant to begin with. He is.

And that is why weary saints can rest.
