You have to really believe that sin ends in death, that you cannot serve sin and Christ at the same time, and that God withholds nothing good from those that walk uprightly. We have a responsibility to keep our heart with all diligence, to ponder the path of our feet, to withdraw them from evil, and to follow after that which God defines as good in His Word. You have to break your commitment to your flesh which has led to this in repentance and bow to Christ to serve Him with no conflict of interest. Until then you are in the realm of darkness and bondage to the devil's lusts. The true good news of the gospel is that through Christ's redeeming death and saving life you can be delivered from the guilt and power of sin which leads to God's wrath- if you'll cooperate with the true grace of God which He offers you. Praying for you.
Titus 2:11-14: "11 For the grace of God that bringeth salvation hath appeared to all men,
12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world; 13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; 14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works."
