I understand where you are coming from. I was an atheist for quite a few years. I did my own thing. Which was mostly drinking, partying and trying to save the world from an ecological disaster. I found it very unsatisfying.
So I got involved in some cults, explored lots of different religions. I danced with Sufis, meditated with Buddhists, sat under Hindu gurus. I even got involved in theosophy, where I found out that evil was real, even if God wasn't.
But God was after me, and he sent many people to tell me the difference God made in their lives. I knew it was real for them. I knew they believed what they believed.
BUT it wasn't true for me!!
I think that is what you are saying???
So I started reading the Bible, just for argument's sake, to say I had done it. I really didn't get what it was trying to say. I believed by this time there was "a god." I just didn't know his name.
Then a man sat down with me and talked to me about repenting from my wicked ways. (My words, not his - he was a kind and gentle soul!)
Suddenly, I realized that Jesus was the Saviour of the world. Then I realized Jesus was MY Saviour. Then I realized I did have to repent, and I gave up drinking forever (33 years dry this month) and it really was a gift from God.
Then God spoke to me. That was a voice like no other. You didn't disobey. He told me to serve him the rest of my life. I have, and he has always been there for me, leading, guiding, encouraging, chastising when needed. And bringing peace and forgiveness into my heart.
And changing me into his image.
Jesus Christ is the only God.
My testimony is all I can give you, since you don't believe the Bible. After 33 years, you know you are either following a lie or the truth. I know I am following "the Way the Truth and the Life."
If you ask anyone who knew me before I believed in Jesus, they are AMAZED at how different I am now. I did not make those changes, becoming a kinder, more loving person. Only God could do that.
As for God answering prayers. Well, he is not Santa Claus or the Tooth Fairy. He is GOD and he is in control. He answers prayers in ways we cannot see or imagine. But never on demand.
My prayer is that you have come here searching and we can all share a word, a testimony or a prayer with you. I will be praying for you, that soon, God will also be come real, and you will repent and follow Jesus Christ all the days of your life.
