Some indeed preach Christ even of envy and strife; and some also of good will:
Note 4 at Php 1:15: Two totally different motives were spoken of here. Some people ministered out of envy and strife--that is, from a jealous and quarrelsome spirit (see note 5 at Php 1:16)--while others ministered from pure motives, right intentions, and good will. Today, as in Paul's day, the preaching of Christ is done both out of love for the Lord and also out of contention and insincerity. Whether the Word is preached from good motivation or bad, the Word is what "works"--not the messenger. Therefore, we can rejoice that Christ is being preached even when wrong motives are behind it.
