There are many things that change when one becomes a christian,and fortunately the word gives us an outline of what we are to stay away from when bearing the name of Christ.
1.)Fornication…..1 Corinthians 6:18-20
2.)Idolatry…..2 Corinthians 6:16-18
3.)Lusts of the flesh…..1 Peter 4:1-3
4.)The devil…..Hebrews 2:9-18
Precious Sheep Of Renown 
Amen! None of us will ever do this perfectly, this side of Heaven. But God is abundantly merciful, forgiving us when we repent and helping us in our times of need. God bless!
