If we have forgotten the name of our God

This describes a situation that could have happened but did not. The writer knew that they had not forgotten the name of God. Here the word "name" refers to God, himself. To forget the name of God is to stop worshiping him. Alternate translation: "If we have forgotten our God" or "If we have stopped worshiping our God" (See: rc://en/ta/man/translate/figs-hypo and rc://en/ta/man/translate/figs-metonymy)
