Passage
Rejoice in [the] Lord always: again I will say, Rejoice.
Rejoice in [the] Lord always: again I will say, Rejoice.
Philippians 4:2 I exhort Euodia, and exhort Syntyche, to be of the same mind in [the] Lord;
Philippians 4:3 yea, I ask thee also, true yokefellow, assist them, who have contended along with me in the glad tidings, with Clement also, and my other fellow-labourers, whose names [are] in [the] book of life.
Philippians 4:4 Rejoice in [the] Lord always: again I will say, Rejoice.
Philippians 4:5 Let your gentleness be known of all men. The Lord [is] near.
Philippians 4:6 Be careful about nothing; but in everything, by prayer and supplication with thanksgiving, let your requests be made known to God;
The verse centers on "rejoice", "lord", "always", and "again". It is saying that the verse draws attention to "rejoice" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "yea I ask thee also true yokefellow..." into verse 5's "Let your gentleness be known of all...", so "rejoice" and "lord" 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 "rejoice" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
