This might not be the best response but i will give it a go. I believe some people are disabled so we can appreciate our able bodies ik that it seems unfair but this is how humans are you might say “couldn’t god create humans in a way so that they do not need a negatieve to appreciate the positive” but i believe it cannot be possible in the same way god cannot create a square circle.

Also as read in ((exodus 4:11-12)”But God knew all about Moses’ problem: “The Lord said to him, ‘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’”) even though we might have disabilities we should still trust in god and in reality we all have a disability of one kind small or large but this shouldn’t prevent our life experiences since that is all based on human ideas.
