What does Philippians 4:14 mean?

Even though Paul was confident in God's provision for his needs, he expressed thanks to his readers for their concern. Their acts of generosity were a way of taking some of Paul's hardship on themselves. And, of course, their acts were the way God fulfilled His promise to provide. Their kindness was an expression of the fruit of the Spirit (Galatians 5:22–23) and reflected Paul's teachings elsewhere regarding kindness to others (Ephesians 4:32; Colossians 3:12; 2 Timothy 2:24; Titus 2:5).

It's important to note that the Philippians shared, or had fellowship with, Paul's trouble. Galatians 6:2 teaches, "Bear one another's burdens, and so fulfill the law of Christ." These believers sought to share in Paul's struggles and supplied resources to help. Paul's "troubles" included marks on his body from being beaten for his faith (Galatians 6:17). Paul's one other use of "trouble" in Philippians is in 3:1 where he says it is "no trouble" to write to them. Regardless of the trials Paul faced, his attitude toward God, as well as the assistance provided by other believers, helped him to continue to persevere.
