I know some skeptics and have told them of the verses He will withhold no good thing, and He provides for the widow. Now they are proving my God wrong and I cannot do anything to show them He is true.
Rose,
God does not and will not withhold anything from you. There's a reason for this hardship in your life.
I lost my home once. I was homeless. I had nothing, no one to take me in.
I felt like God had deserted me, yet deep inside me I knew He hadn't. My friends would not ask me to live with them, my family, no one. All but one woman. A woman that I particularly did not like, and well, I am a cleaning fanatic and don't smoke, and she was the opposite. But a Christian. So, I moved all day my few boxes into storage after having gotten rid of everything else, said goodbye to my little granddaughter as she went off to live with her mom and dad, and numbly went to Diane's home. I stumbled in the door and said I think I need to take a shower. She said "Lis, your bed is all made up for you". I said OK. When I got out of the shower, and went into the living room to go to bed on the couch, she said, oh no honey, the bedroom. I said what bedroom??? she only had 2, and one was her bedroom, and one her daughter's. She said my bedroom. That lady gave up her bedroom for 6 months, Rose for me. I worked cleaning my church, a part time job, and cleaning houses. I was so tired all the time, and had hardly any money. But that time in my life I became so close to God because He had my full attention. There was no one else but me and Him. He sustained me, He provided a shelter for me, and those six months I'd never give up. At the end of them, He provided a great job for me, and a new home. My granddaughter came to live with me and still does. Things have only gotten better. I still have tough times, Rose, and am in the midst of one now, but I know God will see us through yet again. See, there are decisions that we make and we have to walk out the consenquences, good and bad. Everything we do, we reap the consenquences. God will have mercy on us, and compassion, but many times, it's not what He has done to us, but what we have done to ourselves.
God has not moved, Rose. You need to stop focusing on what you don't have, and think on what you do have. Think on the things that are above, not on the things of this world as it says in Colossians. "I would have despaired, had I not seen the goodness of the Lord, in the land of the living". Grab hold and don't give up on Him. He never gives up on you, Rose. Turn the circumstances around. He is waiting for you to do this..
You mentioned reading some books earlier. I would not read those anymore, but rather read everything I could get my hands on that would build your faith up, read the Word. Stay in the Word.
God does more than just sit there and watch. But He is not a "santa claus" handing out things from up there. God has promises for His children, and they all are yes and amen, but every promise has a condition. It always is "IF" you do this that I command you, I"ll do this for you.
