Philippians 2:4

The apostle here, dissuadeth from another sin, which is very destructive of unity and peace, of concord and love; and that is, the sin of inordinate self-love, whereby we regard only our own honour and profit, wholly neglecting the concerns of others. Look not every man on his own things; that is, his own provate advantage only or chiefly, but take care of the things which tend to the advantage of others.

Not but that. Christian may and ought to look at his own things, but not wholly: our regard must extend further than ourselves, and our own things; we must look on the things of others also; we must be as just and true to another's reputation as to our own, and regard both the honour and profit of our neighbour as well as our own: and where Christians are of this public spirit and temper, it contributes much, very much, towards the preserving and maintaining of unity and peace among them.
