Sheep dip.....Your Bible must have this teaching missing:
"And Jesus saw, as he passed on his way, a man who had been blind from his birth. Whereupon his disciples asked him, Master, was this man guilty of sin, or was it his parents, that he should have been born blind? Neither he nor his parents were guilty, Jesus answered; it was so that Godís action might declare itself in him."
Change "blind" with "down syndrome"...
And...it does not change nor make ineffective: For all have sinned and come short of the glory of God..
My bible has that passage, in fact I quoted it earlier today.
