As to the rest, brethren, as many things as are true, as many as <FI>are<Fi> grave, as many as <FI>are<Fi> righteous, as many as <FI>are<Fi> pure, as many as <FI>are<Fi> lovely, as many as <FI>are<Fi> of good report, if any worthiness, and if any praise, these things think upon;
Philippians 4:6 for nothing be anxious, but in everything by prayer, and by supplication, with thanksgiving, let your requests be made known unto God;

Philippians 4:8 As to the rest, brethren, as many things as are true, as many as <FI>are<Fi> grave, as many as <FI>are<Fi> righteous, as many as <FI>are<Fi> pure, as many as <FI>are<Fi> lovely, as many as <FI>are<Fi> of good report, if any worthiness, and if any praise, these things think upon;

The verse centers on "rest", "brethren", "things", "true", "grave", "righteous", "pure", and "lovely". It is saying that the verse draws attention to "rest" and "brethren", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "and the peace of God that is..." into verse 9's "the things that also ye did learn...", so "rest" and "brethren" belong inside that flow. In Philippians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "rest" and "brethren" with trust shaped by these words, not by a vague optimism outside the passage.
