Why is God leading us into the wilderness by turning us around?

Our God, who goes before us, works all things for our good,

just as a person embraces their child.

He has embraced us and led us this far along the path we have walked.

Yet, we did not trust Him in this matter.

Therefore, He turns us around and leads us into the wilderness along a different path.

Why does God turn us around and lead us into the wilderness?

Could it be to train our faithfulness? Could it be to purify us from all impurities within?

Could it be to humble us and make us obedient to His word?
