Am glad to read your story ending is what we need to always think about, yes Jesus Christ dead for us so that we can be saved and inherit the kingdom of God.
Very glad you choose the right path, may the Lord help us day in day out to grow in faith and gives us grace to make it to him.. so we could dwell with him.
Perhaps my testimony is not as in depth as you would like. But I can assure you I did not "just" do what my friend did without much thinking about it. I agonised for weeks over what I should do, if i was saved, whether I was ready to be baptised. I felt that my friend being baptised was my sign. But you're right prayer isn't 100% accurate, I may have misjudged but that does not mean that my action of being baptised was the wrong one, or that my path as a christian now is wrong. I know and believe that Jesus was the son of God and He lived and died for me, I trust in Him as my saviour and choose to lived a life dedicated to him.
