This episode is from Daniel 1:8- But Daniel purposed in his heart that he would not defile himself with the portion of the king's meat, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.

Also, verses from 1 Corinthians 3:17, Daniel 1:1-8, and Matthew 15:10-20.

If some bad habits has tightened its grip on you, claim Daniel 1:8 and trust in God to help you. We can start by having a purpose in your heart, our mind made up, determination, and resolve to live in victory over temptations of the world; including flesh & the devil. So we can claim the victory in Jesus!
