Summary: Here in Psalm 67 we find the purpose of God’s blessing. This purpose, for all the peoples to know salvation, is what makes Psalm 67 one of the foundational scriptures as the Biblical basis of Missions. Psalm 67 is a glorious Missions song.
When I served as Assistant Pastor of the Baptist Church, in Scotland, one of the first things I wanted to do was memorize Numbers 6:24- 26 (quickview) . Why the priority to memorize Numbers 6 (quickview) ? This is because our Pastor would repeat this scripture as the benediction, at the close of every service.
I knew, as the young assistant from America, I would be leading the services when he was away. I realized that you just don’t read the benediction in the Highlands of Scotland. No way! You look directly at the congregation, raise your hands and you “pronounce” the benediction, loud and boldly. This meant that I had to really get to know Numbers 6:24-26 (quickview) . It would not be good to “mess up” on the blessing!
I learned this blessing and was able to pronounce it: “The Lord bless you and keep you; the Lord make his face to shine upon you and be gracious to you. May the Lord lift up his countenance upon you, and give you peace. (Numbers 6:24-26 (quickview) ) Pronouncing the blessing went well for me every time, but I always remained a little worried when I came to the, “lift up his countenance” part.
When I got over the intimidation of memorizing and pronouncing this verse, I realized its great significance. This is the blessing that God himself gave through Moses for Aaron to bless the Israelites. It was the blessing pronounced by Aaron, and later those who held his priestly office, at the public assemblies.
Our passage, Psalm 67 (quickview)  is derived from this Aaronic benediction. The Aaronic blessing is contained in the seven verses of Psalm 67 (quickview) . But here, Psalm 67 (quickview)  goes beyond the blessing in Numbers 6 (quickview) . Here in Psalm 67 (quickview)  we find the purpose of God’s blessing. This purpose, for all the peoples to know salvation, is what makes Psalm 67 (quickview)  one of the foundational scriptures as the Biblical basis of Missions. Psalm 67 (quickview)  is a glorious Missions song. Psalm 67:1 -7 (quickview)
I) Why to all nations? First Bless Us! (Vs 1-3)
Some Psalms are intended for individual worship. In these Psalms the individual worshipper of God should be alone pouring out his heart to God. Other Psalms are for corporate worship, when the assembly collectively gives praise. This Psalm is for corporate worship.
Psalm 67 (quickview)  was probably sung corporately every year at the Feast of Pentecost. As Christians, at the mention of Pentecost, we immediately think of Acts Chapter 2. Our minds take us to the time when the Holy Spirit came in power. This great event happened when Israel was celebrating the Pentecost Festival, thus we call the coming of the Holy Spirit Pentecost. This festival is also referred to as the Harvest Feast.
It came fifty days after Passover. We could compare our American Thanksgiving Holiday in November as something similar for us, as to what the Pentecost was for Israel. A time we thank God for the blessings he has bestowed upon us. The most Basic prayer for any of us is to ask God to bless us. We ask, “Father meet my needs, Bless me!” In celebrating the harvest, there is, especially for the agricultural society, a keen sense of dependence on God. Give us the rain and the sunshine needed to grow the crops and sustain our life. Protect us from natural disasters. A calamity that will destroy them is just a natural disaster away.
