So, you mean he`s sort of motivation a person to make something for example, but you can`t see evidence of it because he`s forgotten?
Well, in my opinion, God never stops knowing things, but He might not let certain things effect what He is going to do. So, in a practical way, He forgets . . . meaning something does not effect or decide what He does.
For an example, God's says He forgets our sins, if we trust in Jesus. Yet, also in God's word we see how our Apostle Paul tells us about how he once sinned. Even so, he can live as though that never happened . . . because of how now he is with Jesus.
So, for judgment it is forgotten, but for an example to encourage us how God forgives, it is remembered.
Then we have how Jesus left Heaven itself in order to reach us and save us. If we say Jesus "forgot" Himself, by leaving Heaven in order to bless us because He loves us > yeah, we could say He "forgot" Himself > meaning He was not going to think about how He was in Heaven, because He was so busy with loving us and caring about us. But on the other hand, He might have been remembering how He is compassionate and caring and able to help us, and this mattered more than just thinking about how great He was in Heaven. And He was remembering how we so needed help.
In any case, we can see how Jesus is not conceited, if He cared more about us, than about staying in Heaven.
So, why does not God make Himself more obvious to each human? We say we can see Him, through His creation. But there are things we do not see about Him, just by looking at creation, right? Can we look at the sun, for example, and know God wants to forgive us and adopt us through Jesus to become His children? But maybe we can see how so many creatures are family beings . . . so we might realize God is about family love and caring and sharing and helping each other. We can see how doing things as family can work better.
But if God is not making Himself obvious through creation . . . in every detail . . . there can be His purpose for this. Creation is not what matters the most. He wants our attention actually beyond how marvelously and wondrously He has made things. Creation might be partly for getting our attention to God, but not to stay only on the fact that God has created things. There is so much more to God, than how well He can make things. He is about family caring and sharing love . . . being personal with His children . . . in our hearts and minds.
So, in order to be with God, we need to be able to sense and feel and perceive deeper than our natural senses. And . . . by the way - - how we are, now, can effect how we see God.
And there is His overall purpose for making all things. His own attention is not mainly to things He has made and getting people to know He made it all. This is more of a beginning realization we can make. But what does He want to bring us to? What about after the end of this earth and the rest of the universe??
This universe is not the end of the good things God has done. So, God is not going to just have people die and then spend eternity saying, yay, You did such a great job of creating the universe. His attention is to much more and better that He has coming. The present creation is part of His plan, but this present universe will no longer exist - - or be remembered, by the way - - once God has done what is His main purpose.
Maybe we could say, He is like the artist who makes such a great painting and he is there at the art show; but he has become so busy with loving and sharing with certain people; they have started to get to know him and find him to be much more interesting than his painting!
In our Creator's love, we discover the best creativity, which He shares with us.
