Why should we return to the Lord our God?

“Be glad then you children of Zion and rejoice, rejoice in the Lord your God, for he has promised that he will restore to you the years that the swarming locusts have eaten, the crawling locusts have consumes, you shall eat in plenty and be satisfied and praise the name of the Lord, your God, who has dealt wondrously with you, because you have returned to Him.” Praise the Lord!
