What is it like to experience walking in the light of the Lord, after you have wandered in darkness and sin?

Have you ever stopped eating something and after a while tried to go back to eat it again? Could you recall how it tasted? For me it tasted different, unfamiliar, it was not sweet, and it made me sick. That is the best way I could describe my experience of walking in darkness and sin and walking in the light of the Lord. Every day Lord, I ask you to plant my feet on higher ground, for my heart has no desire to wander again in darkness and sin, my aim, my hope is higher ground. Thank you, Lord!
