You have a lot of good stuff here, but I think you can lengthen it and get a lot more leg work out of it.
First, I would axe the "I respectfully submit this personal statement..." line. It's not necessary.
Second, flesh out the second paragraph. You could make some really powerful arguments and discuss the impact that was made on you when the woman you were there to help in turn assisted you. This is a very moving image and you kind of just graze over it.
Third, your transition into the third paragraph is a bit abrupt and startling. You go from Managua to your dad dying. You need to prepare us for this. Further, a discussion of your father's untimely death warrants more than a sentence. You write, "My gift has been their example of charity, compassion, and perseverance."- you should show us this with an example. Perhaps you could tie this back in with your work at Managua. Talk about your mother's sacrifice and how even though she was going through so much and had to shoulder so much responsibility she still selflessly gave to you in the way the woman at the barrio did. By doing this you would show that, "Along the way I have met people from all walks of life who have reached out to me with loving kindness, wisdom, and thoughtfulness..." instead of just telling us in a sentence which any applicant can and probably will write.
Fourth, what have you learned at Spring Hill College? Again, show us, don't tell us.
Lastly, your final paragraph can be really powerful especially if you adopt some of my earlier suggestions. That way your claims at the end stem logically from the pictures you have created instead of seeming like something obtusely profound you just came up with to sound smart
Overall, what you've got is good, but you can definitely make it great!
