"All is well" 意思是一切都很好。这句话来源于文艺复兴时期的英国哲学家约翰·牛顿（John Newton）所写的赞美诗“Amazing Grace”中的歌词。
例句：
"Even though things are tough right now, we have to remember that all is well."（尽管现在情况艰难，我们还是要记住一切都很好。）
"All is well that ends well."（结果好就是一切都好。）
"I know it's hard to see the pght at the end of the tunnel, but trust me, all is well."（我知道看不到隧道尽头的光明很难受，但相信我，一切都很好。）
