"because I always wonder (and ask) how one can confidently and truthfully make such a heavy statement."I suspect, and hope the reason you feel and think this way is because the Holy Spirit is indicating to you that haphazardly using the name of the Lord is not a healthy habit to get into. When I was a young believer I always felt like a bit of a black sheep because other believers were so quick to say that God told them something, and I perceived that people were using that statement as a means of self-justification. It bothered me then, and still bothers me now. I suspect it grieves the Spirit. Continue acting circumspectly, it will go well with you, and I hope your walk with the Lord grows and grows every day.
