If God needs infinite praise, then how can anyone who has sinned be able to experience God's goodness? Because God made a promise to us that he would carry out the work he had promised but we can't always understand it all. If the moral good of Christ was not our essential good, what good would be accepted from sinful creatures if good was not essential? 

This is the good thing about sacred word!  God found a way to communicate with the human race. Caringly teaching the divine creation is stamped with the revealed reasons in divine law, covenants, curses, etc.

The key question is, how does God receive the praise of wicked creatures?  If it is absolutely necessary for God to get infinite praises in the moral demands of intelligent creatures, how can any sinner experience the divine goodness of the almighty creator?

Because God has, faithfully carried out the work of creation, but we praise God for the work of salvation that Jesus has done for us. If the moral goodness of Christ was not our intrinsic goodness, what goodness is acceptable from a sinful creature if the goodness is not intrinsic? 

This is why the Psalmist carefully teaches the essential goodness revealed in sacred word!!! God voluntarily proclaims eternal goodness in the proclamation of authority.  Teaching about God's creation is important because it includes divine law, covenants, curses, etc.

It's normal to pronounce the Psalms while you're imagining an ideal kingdom.

92 1 "It is good to praise the Lord and to sing music in your name, O Most High, 2 to proclaim your love in the morning and your faithfulness in the evening" The key question how does God receive the praise of creatures mean? absolutely necessary for God to obtain endless praise in the moral demands of intelligent creatures, how can a sinner experience the divine goodness of the Almighty Creator? Which raises the specific question: If the moral goodness of Christ was not our intrinsic goodness, what goodness is acceptable to a sinful creature if the goodness is not intrinsic? This is why the Psalmist carefully teaches the essential goodness revealed in the sacred word !! !God willfully utter eternal goodness in authoritative statements. Carefully teaching about divine creation is based on the reasons revealed in divine law, covenants, curses, etc. It is quite normal to pronounce the Psalms while constituting an ideal kingdom.
