先说天国里最大的。
耶稣在马太福音18章里说凡自己谦卑像小孩子的，在天国里就是最大的。小孩子的特点是供养完全靠父母或监护人，无忧无虑，天真，单纯，肯服从。因此，凡承认自己无论怎么做都无法拯救自己，而只活在耶稣的拯救，倚靠神恩典怜悯的人，在天国里就是最大的。这样的人能时刻从内心里感受到神的大爱，时刻受圣灵的带领，从而有力量去爱别人和原谅别人，有力量和喜乐做有益的事情，包括传福音。他们清楚律法是让人知罪并知道耶稣已经替圣徒成全了所有律法，所以不再活在律法以下。这些人在基督里所做的工程末日的时候会得到主的奖赏。
希伯来书也提到在基督里长大成人的都熟练义的道理，这个义是神的义，而不是立自己的义(罗10:3)，也就是能分辨好歹。
天国里最小的虽然也相信耶稣或初信，但仍有嫉妒纷争，也可能性情懒惰以至于吃喝穿都靠接济，甚至不检点而坐监，耶稣称他们为最小的弟兄; 保罗称他们为吃奶的基督徒，在基督里是婴儿，不熟练义的道理。有的妄想守住613条律法和十戒，却不知是在废弃律法。他们在末日虽仍得救但所做的工程会被烧毁，得不到主的奖赏。当然，这些人里的一些会在主的恩典里慢慢长大，一些工程会受奖赏。
