I know how you feel. I would go as far as to say my life is cursed. People tell me its not true but my whole life (except a few brief periods) is a stronger testimony than someone who has not suffered any more than minor problems telling me it is not true.
My dad was violent and verbally abusive. I was the youngest of 3 brothers and got beaten up by my older brothers as well (one has since committed suicide as a result of the abuse he received). As I got older I developed health issues. I became a Christian over 20 years ago and had a year or two where I felt blessed and had some miracles in my life, then it seemed to dry up. My whole life has seen nearly every opportunity to prosper and improve my life hindered by the level of spiritual attack I have never seen in anyone else. Its included health issues, personal attacks - mainly lies, being discriminated against (I'm a white male and have been told several times I wasnt given a job despite being the best candidate so they could "positively" discriminate and give it to a woman), I've had my job changed and been moved as a result of company restructures about 10 times and every time been given a choice of working in a job I didnt want to do for managers with incredibly bad reputations (bullies, incompetent, etc) resulting in stress and mental health issues from the environment I was moved to. I cant have most medications due to rare allergies so always end up untreated. Doctors have given up on me. All this has been regularly over the whole of my life and I doubt I have ever gone much more than a year without a major issue against me like having my job changed, being bullied, being told I wouldnt get promoted despite being the best for the job (that really affects your self belief), both before and since becoming a Christian. This is on top of what I would consider normal issues I see other people go through.
I've tried repenting of every sin I can think of and any I am unaware of. I tried pleading with God, commanding His authority over my life, submitting, overcoming and everything in between. Nothing seems to work. Ive preached the gospel to the lost, done good works for the Lord (not in self righteousness), given until it hurts, served god, served the church and prophesied (including God telling me to pray for a church that didnt exist and then a couple of months after I started praying into it people started to feel called into setting it up and I now go there). I consider myself humble (any pride I may have had has certainly been beaten out of me by this life), I have no strength left in myself and have to trust in God for any strength I have. But still I struggle in this world and everything goes against me. The last real miracles I can recall in my life was 1999/2000 when I was delivered from smoking and had some miraculous healing.
Ive also had some major problems with pastors. One in particular turned on me suddenly and really hurt and damaged me. This was after I supported him during a church split and I was one of his strongest backers and had previously been good friends. As soon as I was no longer needed he became extremely abusive and I later found out to others as well. After he was sacked the new pastor wouldnt give me any time and pushed me out of a number of ministries I was involved with at church. I had an opportunity to take redundancy from work and wanted to go to bible college but he locked it, by his own admission because it was his church and he didnt want anyone else in his church training to be a minister which he was worried would lead to them undermining him. Instead I went self employed and ended up being ripped off by someone who was supposed to help me build my business so now have no income and little money left.
This is not like Job who was blessed, then was allowed to be tormented for a while and then received blessing again, this is lifelong suffering. The longer I seem to go with nothing major happening, the worse it seems to be when it does. For example a new manager coming in who is a bully or being moved to a job I hated and having to try to find one I like better which is harder when you are really unhappy/depressed with where you are every day. It soon feels like as soon as you get your head above water you are dragged down again.
Even this morning before reading this I was thinking about promises I genuinely believe were from God to give me a double portion of blessing which have over the years been prayed over me multiple times by numerous people. It has been prayed that I will receive spiritual blessing, financial blessing and just about every type of blessing. This has come from all sorts of people, internationally renowned speakers (at least 3 or 4) and many pastors and ministry teams at various churches and conferences, probably 20-30 (maybe more) people in total over the years all saying the same thing and most not knowing me.
I look forward to nothing in this life now and just want to get to heaven. Most Christians I know would be fearful of the tribulation, I would welcome it as it would mean the end is close. Not waking up tomorrow would be a blessing for me and something I only dont want to happen now as my kids are a bit too young, but give it a few more years.
I just have to hold on to the words spoken over me that when I receive my blessing it will make all of the suffering worth it. That and the scripture that I have on my heart is the rich man and Lazarus. In particular Luke 16:25. If this is true for all of us, which I believe it is, I will have such great blessing heaven that you should all be jealous of me.
