He's reminding me that our relationship was not a one time decision. He's telling me, once again, that I have to choose him every day, usually multiple times. TV or prayer? Angry Birds or Bible? Time to choose.
He's reminding me that there are very few people that choose the way of life because it is narrow. His specific example was that of a healthy and active life versus a destructive and sedentary one. Too few people choose life. Go for a walk or order a pizza? Eating that cookie or eating that apple? Time to choose.

He's reminding me that he still loves me and that I CAN and I WILL have the life he has shown me I can have, if I remain in him.
I am not unique. That life you imagine, you can have it. He has promised good to his people. So let's choose life, again.
