The Eternality of God and His People in Worship

Psalms 102:18-28

18 This will be written for the generation to come,
That a people yet to be created may praise the LORD.

19 For He looked down from the height of His sanctuary;
From heaven the LORD viewed the earth,
20 To hear the groaning of the prisoner,
To release those appointed to death,

21 To declare the name of the LORD in Zion,
And His praise in Jerusalem,
22 When the peoples are gathered together,
And the kingdoms, to serve the LORD.

23 He weakened my strength in the way;
He shortened my days.

24 I said, "O my God,
Do not take me away in the midst of my days;
Your years are throughout all generations.

25 Of old You laid the foundation of the earth,
And the heavens are the work of Your hands.

26 They will perish, but You will endure;
Yes, they will all grow old like a garment;
Like a cloak You will change them,
And they will be changed.

27 But You are the same,
And Your years will have no end.
28 The children of Your servants will continue,
And their descendants will be established before You."

This psalm was written to the completed people of God, chosen in and by Him to be a new eternal people in the Messiah (Romans 2:28-29).  It was unclear when prophetically written here, but now we can look back and see fullness of the promise to Abraham (Genesis 22:18, Galatians 3:8-9) by faith to gather us from all nations to Himself.  His plan was not for one nation alone as Israel, but as a people called to Himself out of all nations as a spiritual Israel (Romans 9:6, 8, 10:11-12).  We are one people, now created by grace through faith according to that promise, that we may all together praise our LORD and God forevermore (Galatians 3:28-29).  God’s great mercy caused Him to look down from heaven’s throne to consider His people who groaned under the burden of their sin and set us free from death (Romans 8:2) to which we all are born into (Romans 3:23) as sons and daughters of Adam (1 Corinthians 15:22).  We therefore as His one people (Ammi), some who were not before (Lo-Ammi) now can praise and serve Him together (Hosea 1:9-10, Romans 9:25-26) in Christ!  Like the psalmist, we fear our days fly past too quickly, yet are not forsaken because He is eternal in the heavens, as is His promise.  He endures forever, who was and is and is to come, who is who He is.  We die but God cannot.  But since He has defeated death, we will be changed however as 1 Corinthians 15:52 and Hebrews 1:12 assure us.  He remains the same, immutable and eternal.  We then continue to serve as His people whom He established forever by promise!  Amen.
