In other words, the need of all people, is met in compassion for all people (namely the gospel of Jesus Christ), that God may receive praise from all people. The gospel is an invitation to come and praise the Lord forever. Let all the people sing!
So, we come not to Christ with our birthrights, upbringings, pedigrees; we bring not our achievements, our deeds, our badges of merit. No, we come like dogs to the table, needy yet hopeful and find that the Master of the house is our heavenly Father.
