I was thinking of this one,
Isaiah 46:10 KJV
10) Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
I'm thinking you are making a distinction between God's self-confidence in His ability to cause things to happen, and His ability to see into times which are future to us.
If I'm understanding you correctly, you are thinking that God knows that His work will prevail, and therefore has the confidence to declare the things that will be, knowing He will bring them about, though He cannot see it now.
Isaiah 44:6-8 KJV
6) Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
7) And who, as I, shall call, and shall declare it, and set it in order for me, since I appointed the ancient people? and the things that are coming, and shall come, let them shew unto them.
8) Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
God gives His unique ability to accurately foretell the future as something that sets Him apart from all so called other gods.
Deuteronomy 4:26-31 KJV
26) I call heaven and earth to witness against you this day, that ye shall soon utterly perish from off the land whereunto ye go over Jordan to possess it; ye shall not prolong your days upon it, but shall utterly be destroyed.
27) And the LORD shall scatter you among the nations, and ye shall be left few in number among the heathen, whither the LORD shall lead you.
28) And there ye shall serve gods, the work of men's hands, wood and stone, which neither see, nor hear, nor eat, nor smell.
29) But if from thence thou shalt seek the LORD thy God, thou shalt find him, if thou seek him with all thy heart and with all thy soul.
30) When thou art in tribulation, and all these things are come upon thee, even in the latter days, if thou turn to the LORD thy God, and shalt be obedient unto his voice;
31) (For the LORD thy God is a merciful God) he will not forsake thee, neither destroy thee, nor forget the covenant of thy fathers which he sware unto them.
Was it God's plan that He would cause Israel to sin against Him, and therefore declared through His servant Moses that it would come to pass, knowing He would cause it to be?
God does not tempt others to sin. But He knew they would.
Psalms 147:5 KJV
Great is our Lord, and of great power: his understanding is infinite.
It sounds as though you believe God's understanding is limited to what He can see today. I don't agree.
Much love!
