Hi Amy,
 
You state that you DO NOT believe that Jesus was speaking about His 'faithful Church', ie. the elect, in His Olivet Discourse, but rather you believe that he was speaking about  the 'unbelieving Jews' at the time of His return at the end of the age in the Olivet Discourse.
 
I believe that He was speaking of His Church who are 'His elect', who are also watching for the sign of His return at the end of the age.
 
First of all, He was instructing His disciples who are believers. They asked Him, " what will be the sign of your coming and the end of the age?"  The unbelieving Jews of Israel are not going to be watching for signs of His return, but the believing Church will be. Then Jesus went on to describe the beginning of birth pains as  signs  to watch for. He is speaking to 'believers' who are His Church watching for his return at the end of the age, not to the unbelieving Jews of Israel. Then He says, he who stands firm to the end will be saved."  He is speaking to His faithful watching Church - not to the unbelieving Jews of israel.
