Joel, prophet to Judah Thru the Bible: Joel At the time of this prophecy, Judah had been hit with swarms of Locusts followed by a devastating drought and Joel was commissioned by God to tell them they hadn't seen anything yet, unless they repent. This book shows, in brief form, the extremes of God's judgment and tender-love. God has a future for Judah and all who will surrender to Him in love and obedience. Blow the trumpet in Zion and pour out God's precious Spirit! Blessings!
