"because I am with them"

3 Nephi 14:14: "Because straight is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." 
'Find' implies action on our part.  We don't just stumble across doing the right things and being on the path to Christ, we have to find it, search for it, and make an effort to stay on it.

3 Nephi 14:16-20: "Ye shall know them by their fruits..." this little scripture block reminded me of Jacob 5, and I think it adds some cool insights to it.  Cross reference it and take a look if you like. :)

3 Nephi 18:4-9: There is a repeated phrase on this page.  That phrase is "and were filled".  I found it interesting that the same wording was used all of the four times the disciples and other ate.  It struck me that we are filled (completed, full, satisfied, etc.) by Christ.  It was a good reminder and a sweet insight about how Christ really does complete us and make us feel whole.

3 Nephi 18:32: "for unto such shall ye continue to minister... and I shall heal them, and ye shall be the means of bringing salvation unto them" We are helping Christ heal and save others when we teach them of Him. :)

3 Nephi 19:22: "they pray unto me because I am with them." Christ was literally with these people, but this verse reminded me that we should always pray to Christ, and that implies that even when he is not physically with us, we should strive to have Him with us always.  This means to live in a way that His spirit can continually abide in us.  It was a good reminder.
