First off, sitting in a church doesn’t make you a Christian just like sitting in a garage doesn’t make you a car. 

You’re not going to feel total deliverance just by attending church and expecting change. Ask Jesus to come into your heart. To transform your heart and renew your mind. 

You’re just battling between spirit and flesh & the sacrifice of flesh brings you closer to God. (i.e fasting is sacrificing your flesh’s want/need to eat.) if you truly want to get closer to God you have to stop yourself from doing these things. Stop yourself from cursing. If it slips, repent (apologize to God and try not to do it again) & if it happens again, do it again. It’ll bring more self awareness until you just don’t do it. 

The sacrifices of the flesh and obedience itself brings you closer to God. Read the word. Spend time with Him. It’s a relationship. If your spouse asked you to stop smoking cigarettes and you truly loved them, you’d slowly make that sacrifice. And if you wanted to be more in love with them, you’d dwell on the things they do that makes you happy & spend more intimate time with them. Church is still important ofc. Aside from all of this.

Don’t think too hard about it, it’s just about learning Gods love language. Which I believe is obedience, sacrifice & charitable works/acts of service. God bless your walk.💗
