请英语高手来帮我看看这句话有没语病？

1） was willing 应为 were willing TO，典型的虚拟语气；
2） a opportunity 应为 an opportunity，冠词错误；
3) 最后的引语加引号。
4) face ... and say 典型的中式英文

所以，全句应为：
If god were willing to give me an opportunity, I could say to all people: "I'm sorry!"

If god was willing to give me a opportunity,I could face all people and say(最好用say) ,"I'm sorry."
be willing to do sth.

有如下几个错误
第一 willing 后面要加 to,固定短语be willing to do sth
第二 应该是an opportunity 不是a opportunity
第三 如果是用say的话就是对的
正确的句子应该是"If God was willing to give me an opportunity, I could face everyone and say, I'm sorry."

If god was willing to give me a opportunity,I could face to all people and say ,I'm sorry.

If god was willing to give me an opportunity,I could face to all people and say ,'I'm sorry'.

或者

If god was willing to give me an opportunity,I could face to all people and say sorry.
