Passage
For good <FI>is<Fi> Jehovah, to the age His kindness, And to generation and generation His faithfulness!
For good <FI>is<Fi> Jehovah, to the age His kindness, And to generation and generation His faithfulness!
Psalms 100:3 Know that Jehovah He <FI>is<Fi> God, He made us, and we are His, His people--and the flock of His pasture.
Psalms 100:4 Enter ye His gates with thanksgiving, His courts with praise, Give ye thanks to Him, bless ye His Name.
Psalms 100:5 For good <FI>is<Fi> Jehovah, to the age His kindness, And to generation and generation His faithfulness!
The verse centers on "for good", "faith", "jehovah", "kindness", "generation", and "faithfulness". It is saying that the verse draws attention to "for good" and "faith", so its meaning should be read from those terms before moving to application.
The prior verse says "Enter ye His gates with thanksgiving His...", giving immediate footing for "for good" and "faith". In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "for good" and "faith" with trust shaped by these words, not by a vague optimism outside the passage.
