I could just use add-on battery packs, but I'd also like a replacement battery pack so if my battery begins to deteriorate, I can get a new one.

我可以只使用附带的电池，不过我还是希望电池可以替换，这样当电池变差的时候，我能够换一个新的。

No matter what I do my body will continue to deteriorate, but, spiritually I can look forward to growth and renewed vigor as long as I listen and then act on what I hear God saying.

无论我做了什么我的身体都会退化，但是只要我听从并按照上帝的知道做的话，心灵上我就会期盼成长并重现活力。
