To understand God fully, you must first know Him. And how can one know Him?
It is written: Luke 10:22 - All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him.
But if you know not the Son as clearly displayed by your responses Ladyfatima, you know not the Father. And no one comes to the Father but through the Son.
First know the Son and develop a personal relationship with Him and then you will see clearly who God is.
O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
For it is written: 1 John 2:23 - Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also.
