Matthew 24:32-34 Now learn a parable of the fig tree;...
So also, when you see all these things, you will know that He is near, right at the door. 34Truly I tell you, this generation will not pass away until all these things have happened. 35Heaven and earth will pass away, but My words will never pass away.
A popular theory amongst evangelical Christians is that the fig tree represents Israel.
The fig tree was "cut down" because it wasn't bearing fruit , (70AD) but it would be replanted, and when it is replanted (Israel once again declared a state 1946) that generation shall not pass away till all be fulfilled
Luke 21:29-32 Behold the fig tree, and all the trees;
when they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand. Verily I say unto you, This generation shall not pass away, till all be fulfilled
For an Adventist View you might try
Ministry Magazine September 1999Here's a quote from that article
Jesus' statement that "this generation shall not pass away" (Matt. 24:34; 26:64) is applied to all major opponents of Christ in every generation. They will all be resurrected at His second advent and face Him as their Judge. Jesus' point is not the chronological life span of "this generation" but His sure coming in judgment for His contemporary generation and for all who have "pierced Him" with their rejection.
Others believe that once the very end of time occurs, that generation will witness all the signs and be living at the second coming of Christ.
Then there are others that say: ?Jesus wasn?t referring to His coming; Jesus was referring to the manifestation of His power and the coming of His kingdom in the transfiguration, (or the resurrection, or the day of Pentecost), because on Pentecost they saw the kingdom of God coming in power.?
