Apparently, this section is a kind of assurance of God s protection. This concept leads us to believe that the dialogue is happening between the psalmist and a pilgrim of some sort. In order to perform an effective contextual analysis, we must first determine what are the criteria in order to make a contextual analysis. The most important criterion is to fit into God s plan. God s plan can be summarized as the salvation for all people through God and others.
Salvation is defined as deliverance from the power and effects of sin.
Since God loves each and every one of us, he wants us to have salvation. In order to recognize that, which God is giving us salvation from, we must look back to the context of Psalm 121. Throughout Psalm 121, there is talk of protecting, guarding, keeping. Obviously, we are asking for protection from sin and the Devil. This shielding from sin and the Devil that we are referring to come directly out of the definition of salvation.
