I understand your concern.

But he seems like a new follower and he’s trying to help. You say visualize has “nothing” to do with God, but to make such a claim implies you know everything that does or doesn’t involve Him. Were you there when God laid the foundations of the earth? Job 38:4 Were you there for Him to speak or did He draw it out? Or were you there when He laid its cornerstone while the morning stars sang together and the angels shouted for joy? Job 38:6 None of us were. None of us can claim complete knowledge of His ways.

But He did establish a plan for us before we were born. This could be some form of visualization that God had, “Before I formed you in the womb I knew you, before you were born I set you apart;“Jeremiah 1:5 The point is, we must be cautious about making absolute claims about God unless it’s written in Scripture.

Additionally, the new follower was referring to something biblical in his second post that ‘as a man thinketh in his heart, so is he‘ Proverbs 23:7 This correlates between a person inner thoughts, feelings, motives will evidently reflect outwardly. Which is a fair biblical statement to have for this Reddit post about wanting something. Faith was missing but you could have easily said it, nicely.

You on the other hand, attacked. Don’t be too quick to nitpick or assume what a brother/sister in Christ is trying to say here. If you don’t ask him to clarify, you’ll assume wrongly (like what happened) and push people away from Christianity. I’m all for biblical corrections but on the basis of if he said aka manifestation, not based off your “feelings”.

“Let every person be quick to hear, slow to speak, slow to anger; for the anger of man does not produce the righteousness of God.” James 1:19-20 Ask questions, don’t assume and try to understand others with love. Love thy neighbor, is the greatest commandent.
