The heart that says “God has forgotten” is often encapsulated in desperate self-exaltation. This is the prohibited exaltation at the cost of others (v. 10). The imagery provided by the Psalmist does not provide relief to the modern reader. For in utilizing the imagery it doesn’t describe a strict accusation but a clear picture of the perversity of the unrighteous. 

One cannot be the faithful who calls upon the Lord (v. 1) when he is crying out “there is no God” (v. 4). So how is one to determine what his heart is truly proclaiming? Inspect how they treat the poor (v. 2), proscribe their level of greed (v. 3) and analyze their pride (v. 4, 6). 

Knowing these things to be true, the psalmist is able to pray that they be brought about now (v. 19). With judgment comes fear and knowledge (v. 20). For salvation to come judgment must come followed by swift repentance.

Some of the earliest texts do not include the destination “Ephesus”. Though a helpful context for the culture, it cannot be depended upon for serious exegetical difficulties. Instead the focus should be placed on who is being spoken to descriptively: the “set apart” of Christ Jesus. This is the church (1 Pet 2:5) destined for militant faithfulness. 

In a hyper-symbolic sense, the consumption of food for life is a type of resurrection. But it isn't so "hyper-symbolic" when one realizes that those who eat and drink Christ have eternal life. He is the bread of life. He has water able to remove thirst. He is the ultimate death that sustains ultimate life.
