The centerpiece of Joel is repentance. After this statement, the theme moves to restoration, renewal of spiritual blessings, and the promise to overcome all enemies.
I am sure that if we do not heed the message of repentance. We will not stand as a nation much longer. We cannot expect the immutable, holy God to pardon us for flaunting such sin and rebellion in His face. How shall we escape if we neglect His Son? Jesus paid an awesome price for our salvation. He did not die to make us comfortable in this world. It is time that we judge ourselves before God has to judge us! Are you not broken hearted at the sin and violence in America? Think back to when things were much simpler in America. Look at the darkness and rebellion that swallows our land now. We are sowing to the wind and we will surely reap the whirlwind without a broken and contrite spirit. Please pray! Please repent! Please humble yourself before Heaven's Majesty.
