What is the meaning of Psalm 102:18?

Let this be written

• The psalmist is moved to record God’s dealings, trusting the Lord to preserve every word (Exodus 17:14; Isaiah 30:8; Jeremiah 30:2).

• Scripture itself testifies that what is written is inspired and profitable for all time (2 Timothy 3:16; Romans 15:4).

• God’s commitment to an enduring, literal Word is underscored by promises such as “Heaven and earth will pass away, but My words will never pass away” (Matthew 24:35; 1 Peter 1:24–25).

• The command models obedience: when God acts, His people testify in permanent form so future readers have an unshakable, eyewitness account.

for the generation to come

• The verse widens the horizon beyond the psalmist’s immediate crisis, echoing God’s pattern of transmitting truth “to your children and your children’s children” (Deuteronomy 6:6–7; Psalm 78:4–6).

• “Generation” signals continuity—each era is responsible to receive, guard, and relay the testimony (Psalm 145:4; 48:13).

• Hard seasons become faith-building stories for those who will face their own trials, proving that the same Lord reigns “throughout all generations” (Psalm 90:1; 100:5).

so that a people not yet created

• God looks ahead to individuals not yet born, affirming His sovereignty over every life (Isaiah 44:1–3; Psalm 139:16).

• The phrase hints at the miracle of spiritual new birth: future believers are “created in Christ Jesus for good works” (Ephesians 2:10; 2 Corinthians 5:17).

• Jesus prayed for those who would believe “through their word” (John 17:20), linking this psalm’s vision with the Great Commission’s reach to generations still unborn.

• Acts 2:39 confirms the promise is “for all who are far off,” cementing God’s heart to gather an ever-expanding family.

may praise the LORD

• The ultimate goal of recording God’s works is worship, not mere history (Psalm 30:4; 102:20–21).

• Praise springs from remembering deliverance; when future readers see how God answered past cries, they are moved to exalt Him in their own day (Psalm 40:3; 145:6–7).

• Scripture repeatedly unites proclamation and praise: “Declare His glory… that all the peoples may praise You” (Psalm 96:3; 67:3).

• Romans 11:33–36 demonstrates the pattern—recounting God’s wisdom ends in doxology.
