Psalm 67 reminds us of God's covenant promise to Abraham in Genesis 12, that He means for all peoples to enjoy Him. By knowing, praising, enjoying and fearing Him all nations can be glad in Him. God blessed Abraham to be a blessing. With the psalmist we're to pray for ongoing blessing in order for us too to be a blessing, a light to the nations today. For this Jesus came and died on the cross. This is why God is passionate about (World) Mission and we're invited to share His Passion.
