Did you ran away from God? You were on fire before but now, the fire is gone? It is not yet too late to go back to God. He will still accept you. This verse is His promise to His people who turned away from Him. You are healed! You are still loved. His anger turned away from you.
Bring back the fire in your heart. Repent and you will be forgiven. Don't turn back from your sins anymore. You will be a new creation if you accept Christ again in your hearts and let Him rule in your life.
