Psalms 128:1

It is here shown that godliness has the promise of the life that now is and of that which is to come. I. It is here again and again laid down as an undoubted truth that those who are truly holy are truly happy. Those whose blessed state we are here assured of are such as fear the Lord and walk in his ways, such as have a deep reverence of God upon their spirits and evidence it by a regular and constant conformity to his will. Where the fear of God is a commanding principle in the heart the tenour of the conversation will be accordingly; and in vain do we pretend to be of those that fear God if we do not make conscience both of keeping to his ways and not trifling in them or drawing back. Such are blessed (Psa 128:1), and shall be blessed, Psa 128:4. God blesses them, and his pronouncing them blessed makes them so. They are blessed now, they shall be blessed still, and for ever. This blessedness, arising from this blessing, is here secured, 1. To all the saints universally: Blessed is everyone that fears the Lord, whoever he be; in every nation he that fears God and works righteousness is accepted of him, and therefore is blessed whether he be high or low, rich or poor, in the world; if religion rule him, it will protect and enrich him. 2.
