Psalm 1 tells Believers to not walk, stand or sit with scoffers, but they are to delight in the Law of the Lord.  In saying that, Believers understand that they are to please God by living holy because it is written, "Be holy, because I am holy" (1 Peter 1:16). During the walk of holiness, vigilance and discernment are key to avoid the pitfalls that present themselves as for the "greater good" when in reality they are clandestine attempts to mock God. To have that discernment, it is essential that Believers constantly meditate on the Word of God to unveil the agendas and attacks of those who oppose God.
