Shall we continue in sin since we are saved by grace? God Forbid, but why?
We are all sinners saved by Grace if we choose. God knows our hearts as He knows every hair on our heads. He knows what you think and what you are abstaining from. You are not acting this out. So keep praying and ask God to take away these thoughts that are not from Him. Read your Bible and pray, listen to some Christian music, anything that will work for you. God will bless you over and over for obeying Him. Trust and obey.
