See here, 1. What it is to make religion our business; it is to follow after righteousness and mercy, not to content ourselves with easy performances, but to do our duty with the utmost care and pains, as those that are pressing forward and in fear of coming short.
We must both do justly and love mercy, and must proceed and persevere therein; and, though we cannot attain to perfection, yet it will be a comfort to us if we aim at it and follow after it. 2. What will be the advantage of doing so: Those that do follow after righteousness shall find righteousness; God will give them grace to do good, and they shall have the pleasure and comfort of doing it; those that make conscience of being just to others shall have the pleasure and comfort of doing it; those that make conscience of being just to others shall be justly dealt with by others and others shall be kind to them.
The Jews followed after righteousness, and did not find it, because they sought amiss, Romans 9:31. Otherwise, Seek and you shall find, and with it shall find both life and honour, everlasting life and honour, the crown of righteousness.
