Self murder and abomination of God are two sins for which you CANNOT be forgiven, according to the Holy Bible. The reason given in the bible (Im going to paraphrase here) that self murder will result in eternal separation from God is that the person who fails to put his faith and trust in God is without God and has not done all he or she could do, because life begins when one puts his or her trust and faith in God.
Now, as a 40 year old, who has been 22 and had very similar circumstances and a very similar attitude at that age.....please dont give up five minutes before the miracle. It is when you reach the place you are right now in your life, attitude and understanding of life, that things can be substancially and remarkably changed.....and this time in your life is crucial for your development and growth with God.
When YOU realize how meaningless life is for you, then you are at a place, personally, that is empowering and can be life altering. I know, I've been there.
Around the age of 23, I felt EXACTLY like you do. That is when I prayed and started looking for God to open up avenues for my life. I realized much later that if I had not been through the experience, I would have wasted away the opportunities, had they come before the self realization and self change. When I was 23, I had a very strong desire to not live the rest of my life like I was living at 23. I was living paycheck to paycheck (and not getting anywhere except maybe a little further in debt). I decided within myself to change my course and join the wide world of people who have financial success, business success, and a REAL LIFE.
I started to take my job serious, and prayed that God move mountains to help me reach success. For that, God gave me newer jobs with more responsibilities and money.....and as I did well with each, more and more opportunities happened. I met and married a wonderful man, formed a family, and became A RESPONSIBLE ADULT......my priorities had to change and they did.
Today, I am in the top 5% of income earners. I have financial success, a wonderful and fully intact marriage, well adjusted children, and most of all, I live without real fear, because I have practiced putting my faith in God for so many years, that I KNOW He cares for me and moves mountains in my life.
I have been richly blessed by the Father, and have a track record to prove it...so it is easy for me to know that you will be ok and that your life will unfold in many beautiful ways.....You may not know that right this minute, but all you need to do is put your faith out there to Him, and then put one foot in front of the other......making your choices ON PURPOSE as you go your way.
