To have an idea of something is completely different from having full knowledge of it.
If pharaoh had, had the fully knowledge of God, he wouldn't have said
"Who is that God that said I should let His people go"
Knowing that God exist is totally different from having the full knowledge of Him
By Apostle Eliphaleth
But Pharaoh said, “Who is the Lord? Why should I obey him? Why should I let Israel go? I don’t even know who this Lord is, so I refuse to let Israel go.”
Exodus 5:2 ERV

After reading the above statement and bible scripture, you will agree with me that there is a very big gulf between having an idea of who God Almighty is and fully knowing who He is.
It is a terrible thing, to just have an idea who God is because of it adverse effect on one's life. Having a full knowledge of God make one to freely flow in the aboundant and amazing grace of God and operating in this grace of God make one above all power of darkness .
To have an idea is like to being ignorant of who God is and God make us to understand that people perish due to ignorant. When one is ignorant, he or she will not know about his or her place in the heart of God. To everyone God thought towards us are of good thought and when one is ignorant of this fact he or she become succeptible to the plan of the wicked.
I pray God open our eyes to see, ears to hear and our heart to understand so as to know Him fully. Thanks for reading.
Remember if you have not giving your life to Christ Jesus now is not to late to do so and be save.
