For a generation to not know God will mean that the previous generation failed to make Him known. Knowing God has to go beyond  informational knowing to relational knowing. This is the level at which intimacy happens. In scripture, the act of love making or intimacy between a man and a woman is referred to as ‘knowing’. Gen. 4:1, ‘Adam knew his wife and she brought forth a son.’ According to Ps. 145:4, it is the responsibility of one generation to make God known to the next. The believer who truly believes in God will go beyond ‘trembling’ and make Him known to the nations as he has been commanded.
