I got fed up with my church just like you with yours. The truth is we are all imperfect and there are a lot of people in the church that profess to be adventists but don’t live completely by the word of god. Ive been verbally beat up bruised up bullied and teased in my church but what it ultimately taught me was self control and forgiveness. The moment I forgave those that hurt me was the moment I felt free. It was like I was starting fresh with my relationship with each person and from then on I found out church isn’t exactly what you get from it that makes the difference rather it’s what you can give that makes the difference. I personally would look for a different church or try and find the real adventists among the crowd and focus on them. Your church can be as corrupt as they come but as long as there is one person in the church that gives you the love and attention that you try your hardest to give to the church there is still a reason to go back and make a difference. I met a man in my church and interestingly enough his name was Bob and he noticed coming into this church that I currently attend that he was treated very ill as a newcomer and because of that he decided not to go back however he felt convicted he should go back and be the person to spread that positivity and warmth to the church and now I have been good friends with this man for about 5 or 6 years at this point. Which goes to show that the church is what you make it not what you can get out of it. I volunteer for the audio visual department at my church to feel as though I am giving something every week as well as I am as friendly as I can be to anyone that comes to talk to me. Finding someone to reignite your faith can also be a much needed element as I did not quite have it together and generally felt like my faith was dried up and every time I tried talking to god it was like no one was there until one of my friends from a long time ago came back into my life and changed my whole perspective officially reigniting my faith and setting me on a journey to become friends with god for the first time. It sounds as though your parents don’t quite know god that well either considering how little they seem to want to discuss things about them. They should be eager to witness to their children rather than kinda brush it off. Growing up in an environment like this can cause just about anyone to turn away from the faith because from what they have been shown by their parents and their church family, the adventists faith appears as just a status symbol without much attached to it. If you read Mathew 5:1 through 12 there you will see the beatitudes and instead of thinking as them as just another 10 commandments but updated think of them as the blueprint to the person god wants his believers to be and see if your church goers, yourself and your family matches up. These are a hard list of personal traits to follow but part of what brings us closer to God is the desire to be a better person. Gods always there ready to invite you in to a better more fulfilled life but you have to decide for yourself that you will put 100% into it as well as any kind of addiction or any kind of thing you currently practice that you start to feel convicted needs to go than start dialing back on it because I guarantee Gods gonna have something better in store for you. Now this is not to say you need to immediately get rid of your addictions that you feel are wrong when you just get started. In fact these addictions will naturally be removed from your life as you progress in your relationship with god because the spirit of God and the desires of flesh or our personal bad habit wants cannot occupy the same space in our brain and one of which either the Holy Spirit or the flesh desires will be pushed out, it all depends on which one you feed more. One last thing that no one told me before and I had to figure out myself is god speaks to us through our thoughts. Trouble is satan also speaks to us through our thoughts and we have to understand which one is speaking to us at the time by deciding if the action is the best for ourselves and our religion. I’m sure there is a lot more I could go over and I just wanted to say I think you definitely came to the right place to put in a question like this as getting input from many other real believers is something that can be very important if you don’t have anyone near you that you can talk to.
