Psalms 102:18

This shall be written for the generation to come - It shall be recorded for the instruction and encouragement of future ages. The fact that God has heard the prayer of his people in a time of trial shall be so recorded and remembered that it may be referred to in similar circumstances in all time to come, for he is an unchanging God. What he has done now, he will always be willing to do hereafter.

And the people which shall be created - Future generations. Each successive generation is in fact a new “creation;” each individual is also; for the essential idea in creation is that of bringing something into existence where there was nothing before. There is a “beginning” of existence in every human being. Man is not in any proper sense a “development” from former being, nor is his life merely a “continuance” of something which existed before.

Shall praise the Lord - Shall praise the Lord for what he has now done; shall learn, from the great principles now illustrated in regard to his administration, to praise him.
