The Sign of Your Coming?

Did Jesus promise a sign before he comes for the church? What will that sign be? Can we know the day that sign will take place? Are we commanded to count the days (after that sign) until Jesus comes for the church? Are there any clues as to the year Christ returns for the church? Is it true that no one will know day and hour? Это и многое другое вы найдете в книге The Sign of Your Coming?
