The truth is that we must praise the Lord our God at all times and Psalm 67 is an exhortation to all the earth to praise the Lord. So, through some verses of this valuable Psalm, let us rekindle that flame of worshiping the name of our God, for He is worthy of all praise and glory.
5 Let the people praise thee, O God; let all the people praise thee.
6 Then shall the earth yield her increase; and God, even our own God, shall bless us.
7 God shall bless us; and all the ends of the earth shall fear him.
Psalm 67:5-7 (KJV)
Spurgeon said about verse five, that although we see a mere repetition in the verse, it is a way of giving importance that all peoples have to praise the Lord. In addition, this is a poetic way in which the people of Israel wrote, an emphasis, so that the importance of said writing is felt.
