Both verses 5 and 6 also tell the same story, that the arrogant will not stand in God’s presence. The liars will not make it through this life alive in this world to the next; the deceitful and bloodthirsty will be destroyed as well. You see David is saying in the context of his prayer to God, the enemies of God are the enemies of David but the people of God also need protection from those who separated from His presence. When God’s word tells us that God “abhors” the wicked, liars, bloodthirsty, deceitful, arrogant and evil people then we too must be like God.
Can we hate the sin and the sinner? God does. How do we get past this idea of hating the sinner whom David describes here? I thought we were to love all people? We are just like Jesus, He loved the wicked sinner but did not tolerate their actions toward God or His children. Abhor means, regard with disgust and hatred. That is what we are to do too, regarding these evil practices and people.
Let us learn here the solemn truth of the hatred which a righteous God must bear toward sin. He has no pleasure in wickedness, however wittily, grandly, and proudly it may array itself. Its glitter has no charm for him. Rest assured, Christ will not live in the parlour of our hearts if we entertain the devil in the cellar of our thoughts.(CHS)
