四、认识人的脆弱——第二个有特殊意义的名字是以挪士，以挪士的意义是“脆弱、必死的人。”人堕落之后，不但人生变为虚空，人也变成脆弱必死。我们必须承认我们既脆弱又软弱，非常容易破碎。我们何等容易失败！人是必死的！没有人能夸口，他下礼拜一定活着。没有人知道他的明天如何。要逃避人第二次的堕落，我们必须认识人生的虚空和人的脆弱。我们若有这个认识，就不会信靠自己;这样，也就不会离开神的路，自以为是了。
五、呼求耶和华的名－那“我是”——当我们看见不该自以为是，乃该照神的方法为神而活并敬拜神，又认识人生的虚空和人的脆弱之后，我们会说，“主阿，我不该自以为是，我必须照你的方法为你而活并敬拜你。主，我的人生虚空，我是脆弱且必死的。”当我们看见我们人生的虚空，我们自己的脆弱，我们就会自然而然的呼求主名。这就是为甚么创世记四章二十六节说，“那时候人才呼求（直译）耶和华的名。”从人类的第三代以挪士开始，人才认识他们的软弱、脆弱和必死，而呼求主的名。
在希伯来文里，神这名称最初是用在创世记一章，神与造物的关系上;“耶和华”这名是从创世记二章开始，用在祂与人的关系上。耶和华是神来与人发生亲密关系时的名。因此，创世记四章二十六节不说人呼求神的名，而说呼求耶和华的名。人不是呼求那位创造万物者，乃是呼求那与他们非常接近，非常亲密的一位。耶和华这名的意思是“我就是那我是”（创四26，参出三14）；就是说，祂是从永远存到永远的一位。祂是那昔是、今是、以后永是的一位。祂是那永存者。当人看见自己的脆弱和必死，他们就开始呼求耶和华那永存者。这就是呼求主的名。这呼求从人类第三代就开始了。
当我们对神不在意时，我们不会呼求祂的名。然而，当我们认识必须用祂的方法为祂而活并敬拜祂，并且当我们认识自己的脆弱和必死，我们的人生不过是虚空时，我们自然而然的，会从深处祷告并呼求主名。

The Way of Escape (2) – Gen. 4:26
IV. Recognizing Man’s Frailty
The second name with special meaning is Enosh. The meaning of Enosh is “frail, mortal man.” After man’s fall, not only did human life become vanity, but man himself also became frail and destined to die. We must acknowledge that we are both fragile and weak, easily broken. How easily we fail! Man is mortal! No one can boast that he will surely live next week. No one knows what his tomorrow will be like. To escape from man’s second fall, we must realize the vanity of life and the frailty of man. Once we have this realization, we will not rely on ourselves; thus, we will not leave God’s way and act as if we were wise in ourselves.
V. Calling on the Name of the LORD — the “I AM”
When we see that we should not be self-reliant but should live for God and worship Him according to His way, and when we recognize both the vanity of life and man’s frailty, we will say, “Lord, I should not rely on myself. I must live for You and worship You according to Your way. Lord, my life is vanity. I am frail and mortal.” When we see our own vanity and frailty, we will spontaneously call upon the name of the Lord. This is why Genesis 4:26 says, “At that time men began to call upon (lit.) the name of the LORD.” From the third generation of mankind, beginning with Enosh, men realized their weakness, frailty, and mortality, and thus began to call upon the name of the Lord.
In Hebrew, the name God is first used in Genesis 1, in relation to creation; but Jehovah is first used in Genesis 2, in relation to man. Jehovah is the name of God when He comes into an intimate relationship with man. Therefore, Genesis 4:26 does not say that men called upon the name of God, but upon the name of Jehovah. They did not call upon the Creator of all things, but upon the One who was near to them, intimately related to them. The name Jehovah means “I AM THAT I AM” (Gen. 4:26; cf. Exo. 3:14); that is, He is the One who exists from eternity to eternity. He is the One who was, who is and who is to come — the Ever-existing One. When man realized his own frailty and mortality, he began to call upon Jehovah, the Ever-existing One. This is the meaning of calling on the name of the Lord, and this calling began from the third generation of mankind.
When we are indifferent toward God, we will not call upon His name. But when we realize that we must live for Him and worship Him according to His way, and when we realize our own frailty and mortality — that our life is but vanity — then spontaneously, from deep within, we will pray and call upon the name of the Lord.
