1 Peter 1:22-25

Being Begotten Again Of The Living And Eternal Word of God Has Purified Their Souls In Obedience To The Truth, And This Must Work Itself Out In Love For One Another (1 Peter 1:22).

He now outlines what should be their resultant behaviour. In all the Apostolic letters the expounding of divine truth leads on to the requirement for righteous living. ‘For, All flesh is as grass, And all the glory thereof as the flower of grass. The grass withers, and the flower falls, but the word of the Lord abides for ever.'

Peter now backs up the imperishable nature of the word of God from Scripture (Isaiah 40:6; Isaiah 40:8). Men are made of flesh. And flesh is like herbage, it withers and dies, and its glory dies with it. All its glory is like the flowers that grow from herbage. They flourish for a while, and they make such a display, and then they wither and the flower droops and falls. But the word of the Lord abides and flourishes for ever. This ‘word of the Lord' is speaking primarily of the word of the Lord which is God's effective voice. It has in mind that God speaks in men's hearts resulting in a transformation which will last for ever. But it includes His written word, when enlightened by the Spirit, for that is one of the instruments that He uses.
