I do not judge I testify and seek to reasure those who know. Those who question have some reason for the question and if it is they do not have the answer then they need to seek it. I have found that many who ask questions have doubts also.
Those with doubts need to be given some method of how to get assurance.
First, I'd like to point out that it would be a tremendous improvement to your posts for you to properly use the "quote" function of this forum.
Second, is assurance really the goal here?
For me, I seek after the truth, not assurance. Giving me assurance of something that may not be true is, well, like building an awesome house on a beautiful, sandy beach. I'd rather keep my doubts and my questions until I find the bedrock of truth I'm looking for than ever settle for the shifting sands of assurance that are so often handed out.
So, thank you but no thank you. If the question needs to be answered, it is because the person hungers and thirsts for the truth, for righteousness, for the true goal of our salvation. IMO, the Holy Spirit is active in the life of the doubting skeptic who keeps asking the tough questions.
Again, reread John 5:39. It was not quoted as an attack to you. If I had meant it for you, I'd have quoted your preceding post. I did not do that. However, you heard it, and were challenged by it, and that challenge formed a question within you, which you posted. Did you post this question in search for assurance, or in search of an honest answer? My hope is that you are confident enough to not need my assurance, so it was likely the latter.
Likewise, the Holy Spirit, working within the OP and others who have such questions, is challenging them in such a way that doubts and questions are formed. They ask these questions and entertain these doubts, not because they are in more need of assurance, but because they are being naturally led toward the firm foundation of the truth Jesus testified about in his sermons.
Encourage the journey, the questions, the searching, and the doubts. These things are not threats to one's faith, but evidences of it.
