I was standing at the blackboard writing: "I will never do whatever it was that I did" one hundred times. I don't remember now what I did to earn after school chalkboard work, but I did earn it. I decided to quit school on the spot and started to walk out. That didn't go well either. I had to finish those sentences.
In Jeremiah 18:6-8 we read: “O house of Israel, can I not do with you as this potter?” says the Lord. “Look, as the clay is in the potter’s hand, so are you in My hand, O house of Israel! The instant I speak concerning a nation and concerning a kingdom, to pluck up, to pull down, and to destroy it, if that nation against whom I have spoken turns from its evil, I will relent of the disaster that I thought to bring upon it. (Jeremiah 18:6-8 NKJV)
As God deals with nations so He does with people. If a nation turns away from God, he can remove the blessings He has given them the same as with a person who rebels against God. The first result of sin is the loss of blessing. Secondly, you lose relationship with God because sin separates you from Him. Finally, you lose your peace. But God is merciful. If you will turn to Him you will find He is always ready to put you as clay back on the wheel. He will form you and shape you and fashion you according to His plan. Take a little test. Have you drifted? Does it seem that blessing is missing? Have you lost hope or peace? If so, you can't remedy this by writing sentences on a chalkboard, but you can return to The Lord, renew your relationship with Him and be restored to hope and peace.
