I completely agree with you. I wonder how God talked to you.
I've been saved just over 50 years. God has spoken to me about 40 times over that time. It is a noiseless yet clear word, usually very concise. Another time the Lord asked me, "What is your righteousness?" I thought about it. My definition is, "The best I can do". Then I remembered what God has to say about my righteousness - filthy rags. That was all for that time.
It's not in the mind, it is deeper than that. It's hard to describe. I know what thoughts are. I know too that when God speaks, it is in my spirit man. Sometimes the Lord simply reminds me of His word. I was wrestling with a sin that I could not overcome. I asked the Lord to help. He said, "Resist the devil and he will flee". This was the answer. I thought that the sin originated with me. I was fighting the wrong enemy. I started to resist the devil every time the temptation came. I had the victory in a few days.
Sometimes God speaks in answer to a question. From time to time, He breaks through my thoughts to talk to me about what He sees I need to know or be reminded about. I'm well aware that Satan can implant thoughts that may seem to be from God. I always check against God's word. I've had to reject some thoughts because I realised they were not from God. We need discernment all the time.
