God calls us all in a similar way to hear His Word and know what the future holds. As Jacob also said in the next verse, "Gather yourselves together, and hear ... hearken ...". All through history God has called to those who desired to be truly wise to hear His Word.
Solomon portrayed wisdom as a person crying to humanity in its busy life to stop and hear. "Wisdom crieth without: she uttereth her voice in the streets" (Proverbs 1:20). And two verses later, "Turn you at my reproof: behold, I will pour out my spirit unto you" (Proverbs 1:23). In fact, wisdom is a Person - Jesus Christ.
God called out to Adam, the first man after he had sinned and plunged the human race into a fallen estate. "And the Lord God called unto Adam, and said unto Him, where art thou?" (Genesis 3:10). When Adam listened, God not only pointed out his problem of sin, but told him of a coming Saviour who would be born of a virgin and suffer to pay for our sins.
When that Saviour came, He went about teaching and preaching and calling people back to God through Himself. "Come unto me, all ye that labour and are heavy laden, and I will give you rest" (Matthew 11:28). This call was repeated by the Apostles and those who know the Lord are commissioned to repeat the offer of free salvation down to this very day. How sad that so many turn from the Gospel message with distaste or disinterest.
The world today has repeated the reaction of the men of Christ's own day. "O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not" (Matthew 23:37).
