You have attempted to explain why you believe in your GOD and religion and not why you DON'T believe in other GODS or their RELIGION, which was essentially my question. Also, I had a little trouble following your explanation, are you stating you felt a strong impulse to Surrender completely and just decided to practice blind faith and as a result of that choice more was revealed to you that acknowledged that the choice you made (to surrender) was the right one.
Not a problem, I understand what you're asking and don't mind elaborating a bit more.
In a nutshell, my reason for disbelief in the gods of other religions and faiths is that none of them have ever demonstrated their divinity or left any solid reasons with which to fully believe they exist (same reason most nonbelievers give). Certainly one can engage in the act of belief of other gods, but it will only be one-sided participation. We have over a billion Muslims and a over a billion Hindus in this world and none of them have a personal relationship with Allah or Vishnu/Krishna/etc....from my perspective, that's truly blind faith. Only Jesus Christ has lived, died and risen and demonstrated his divinity to others. For me, the key to my belief in Jesus Christ comes down to two things: his resurrection and the indwelling of the Holy Spirit in believers. It's the tangible presence of the Holy Spirit that validates scripture. Certainly there are others that have come to belief differently, but this is me we're talking about. Others mock the idea of faith and initially faith is about taking a leap into the unknown, but that absolutely resolves when one truly seeks to know Christ. That initial leap transforms into full assurance in the heart for believers. All that Jesus Christ said about salvation and the Holy Spirit is correct and repeatable today. He opened the gate that leads to him, but we have to be willing to walk through it first in order for a revelation in our lives to occur.
As a child and young adult I was a believer in Christ, but I walked away from my faith....arrogance, thoughtlessness, pride, vanity, etc....were huge factors in that. Later, when at my most hopeless and desperate, when I had exhausted all my own ability to help myself, I surrendered to God Almighty and his presence filled me and the room I was in the most powerful way I've ever known.....it fully changed me. Do I belief I was lead to reestablish my faith? Perhaps, but I can't say for certain. I do know I wasn't living out my faith at all prior to that....I had wholly stepped away from it.....I lived for me and this world. I surrendered to God when I had nothing left and man did he respond! Again, I take no credit for the change, it's all about him. For me, the most powerful proof of God came when I became part of that very proof that I sought. I took a leap of a faith because I desired to know Jesus Christ and when the ruler of this universe reveals himself to you personally you don't anything else....at least I don't.

Hope that is helpful, but also note that my references to Islam or Hinduism is not meant to be disrespectful or combative in any way towards Muslims or Hindus.
