God holds together what He created.  The universe does not fly apart because of God.  You are becoming His new creation.  You may think it is all going to fly apart; but the one who called you can keep you.  The One who loves you will see you through the darkness and bring you to the light.  Do not despair.  You can overcome.  “You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world.” (1 John 4:4 NASB).  “Therefore do not throw away your confidence, which has a great reward. For you have need of endurance, so that when you have done the will of God you may receive what is promised.” (Hebrews 10:35–36 ESV).  The God who takes care of creation is at work in your heart and life.  Be encouraged. 

“For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things have been created through Him and for Him. He is before all things, and in Him all things hold together.” Colossians 1:16-17 (NASB)
