Ok so zooming in to the texts in question .
13But he that shall endure unto the end, the same shall be saved.
14And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
So observations are .
Its the Book of Matthew .
And Jesus is speaking to the Jewish diciples about end times.
I got tired so I won't spend too much time on it tonight. However, this should be a good start to demonstrate that the idea of enduring until the end is incorporated within the scriptural definition of Faith that saves.
In one passage Matthew 24 one might think that he is talking about enduring the great tribulation. However there are many more passages where something similar is stated. What we can discover is that in many ways they all lived this life. They were persecuted, were delivered up, were put to death and had to endure unto death with a promise of eternal life. The principle applied to them at the time, all saints between their time and ours, and it applies to the saints who will be alive at the very end before Jesus returns.
Matthew 24
12And because iniquity shall abound, the love of many shall wax cold. 13
But he that shall endure unto the end, the same shall be saved. 14And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Mark 13
10And the gospel must first be published among all nations. 13And ye shall be hated of all men for my name's sake:
but he that shall endure unto the end, the same shall be saved.
Matt 10
16Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. 17But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues; 18And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles. 19But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. 20For it is not ye that speak, but the Spirit of your Father which speaketh in you.
22And ye shall be hated of all men for my name's sake:
but he that endureth to the end shall be saved.

lest that which is lame be turned out of the way; but let it rather be healed.
