You have the friend that you wish for; someone to cry with you over your sin.

【翻译】现在你有一个你所期待的朋友，愿与你一起为你的罪过而哭泣。

【分析】本句使用了分号，说明是两个并列的成分。第2分句看作省略了you have：

you have someone to cry with you over your sin.

可用更简洁的表达方式：

You have the friend that you wish for: someone to cry with you over your sin.

You have the friend that you wish for --- someone to cry with you over your sin.

over，介词表原因，“因为，由于”。又如：

I regretted over my failure. 我为我的失败而遗憾。
