One can’t know God at all least He come to you Himself and open in you who He is and all of His heaven in you. Not even Jesus could escape this fact proven in Matt 3:16.
Beliefs about a god are not real, only speculations.
The stark reality of knowing God is when you see Him as He is as all of these we read of saw He who is a Spirit and became like Him to know this difference with that renewing of mind started in Adam proven in Gen 3:22. Abraham, Moses, Mary, Jesus in Matt 3:16, 120 in n upper room all became like Him, and in 1 John 3 we read that when you yourself see Him as He really is, ye shall be like Him just as all of these became like Him.
Question is --are you like Him, in His same image that He creates man to be by the Spirit of Love that God is, and do you walk in it as all of these became we read of? If not, then your own salvation is in question.
