Thanks for the greeting, I look forward to learning. I have been having alot of health problems and feel only God can help me with it. The doctors don't seem to know what's wrong. I wish I didn't give up hope so easily but it seems when I ask God for help and nothing happens I get discouraged and give up. Now not sure if it's correct or not but a friend said that a prayer is ignored if the person is not saved. If this is true then i see the problem..
I think the strain of being separated from God can cause health issues. I suffer from psoriasis and it got very bad over the last few years, but since I have come to know God over the last few months and received the relief and peace of knowing He loves me, the changes have been miraculous! The symptoms are decreasing by the week, I had two patches of flaky skin on my legs which are almost gone now, and my fingernails have regained their strength!
I disagree with your friend's comment, prayers are always heard. The issue is that God has the perfect plan for your salvation and you need to learn to accept that the cards you are dealt are given for a purpose. Once you learn to see things positively I suspect your body will be healed not just through the hand of God, but through the peace you attain by knowing that God loves you. The spin-off of stress should not be underestimated.
As for your question how to accept God, you really need to investigate within yourself what particular hurdles you are facing and apply some effort to understand and correct them. We all face hurdles as we adapt from not knowing God to knowing Him, but these are not intended to be a hindrance, they are intended to be overcome as a means to strengthen your faith. Life is a process of learning how to get to know God, make sure you apply a decent effort to understanding His point of view, He has suffered so much heart break over time from rejection and all He desires is that we will come to know how much He loves us. The gift of knowing His love is the most valuable treasure you can find, make sure you keep digging for it, it's right there where you are standing!
As others have said, begin by reading the Word and seeking to know all the truths in the book. Once you have a solid understanding of all that He has revealed to us in the book, you will have already discovered the reality of Him and you'll be just as content as any other Christian who knows Him on the personal level. Look at it as though the absence of God in our lives is a sickness, and the knowledge of God is the cure. The means to attain the cure is to learn the truth that He has provided for us in the Bible. Make sure you bring any difficult passages to discussion, the most harmful thing you can do is reject the Bible because this breeds a grudge against God. He never intended for us to be confused by the Bible, such confusion is evidence of some hurt we are harboring which prevents us from accepting God's point of view, thinking we know better than He does. Apply your efforts to develop a humble attitude rather than a proud one, we humans have no such right to believe we know better than God does, thus we should always seek to learn from Him rather than contest Him.
