Psalm 80:18-19 So will not we go back from thee: quicken us, and we will call upon thy name. Turn us again, O Lord God of hosts, cause thy face to shine, and we shall be saved.
The troubles the nation is undergoing are caused by their own sin and unbelief. The Psalmist here repents and pleads for mercy and salvation. He promises they will not go back from God again. He asks God to give them life (quicken), and they promise to call upon the Lord in faith and worship. He asks the Lord to come among them and smile upon them and they trust Him to save.
We also admit that our own sin is the cause of the troubles we face, and we repent and ask forgiveness. We daily renew our faith and call upon Him. We arise and walk in newness of life. He makes alive, smiles upon us with grace and favor, and saves us. We are overwhelmed with love so that we respond with perpetual thanksgiving in our hearts.
