To me it is a perplexng problem. Jesus identified the people he was talking to in the sermon on the mount when he said, "Ye are the salt of the earth" and "ye are the light of the world". I can't find anywhere later in the discourse where he changes the group he is talking to and says to this same identified group in chapter 7, "Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." It appears only few of the salt and light group enter the straight gate. Jesus seems to echo this when he is straight out asked "Lord are there few that be saved?" and Jesus' response again is to, "Strive to enter in at the straight gate". I'm sorry but to me striving is not grace and again Jesus appears to say few are able to strive enough to enter. This seems to contradict what was told to Abraham when he was told his decendants, the children of faith, would be as numerous as the stars in heaven and the sand at the seashore. It cannot be both "many" and "few" at the same time so Jesus must be talking about something other than being a child of God, which we know is totally by grace, here he is talking about something that must be strived for and the child of God may miss. Indeed he seems to imply most will miss it. The ones who miss it end up in "destruction". Since I believe that every spiritual child of Abraham, which are many, will be in heaven without the loss of one just what does it mean for these people identified as salt and light to wind up in destruction? I have my own answer but I've run out of time right now to post it and I'll try to get back on later
