The #1 difference between Habakkuk and his peeps was attitude.  This is also the #1 quality that you will see in someone spiritually mature vs. younger in their faith.  Habakkuk grew in his faith as he developed his intimacy with the Lord.  He once felt frustrated and annoyed, with maturity he felt trust and peace. He once felt confused, he then had understanding.  He once felt fearful, he then had faith in the future God had planned.  The only thing that changed his perspective…time with God in prayer and His Word.  This brings spiritual maturity. Without it we will be tempted to live driven by our emotions vs. character.
