Would you say it is unwise to be unjust? Would you also say wisdom is part of what God knows through his omniscience? If so, would you say, as well that God’s omniscience limits what he will do?
God certainly does not limit Himself. You for instance neither limit yourself by NOT killing your enemy, even when you could and nobody ever could possibly find out. You would not, because your conscience tells you it’s wrong, and doing wrong, sinful things, spoils and smirches your soul. Your soul which is your actual “I” and yourself.
If then someone would say “you limit yourself”, or “you can not” because you do not, then you’d wonder about his lack of understanding - for you very well could, but doing such thing wouldn’t even come into your mind, so, why should you “limit” yourself by not doing what you could - killing your enemy.
With God it’s neither limiting Himself, for God is love itself (among justice and righteousness itself and goodness itself). But one must beware to challenge this love of God, for then it’s as Paul warned in Hebr 10,31: a fearful thing to fall into the hands of the living God.
Yes, to be unjust is indeed extremely unwise, for justness is given to us by God together with our birth. Some though bury this justness for selfish reasons, and so cripple their soul, which is outmost unwise, as to live with a crippled soul is to live with a crippled self. It’s as unwise as to decide not to eat.
We know all that and a lot more about God and our relation to God, through God’s owen revelation to us. God revealed Himself to us (through Moses - the Prophets, Jesus Christ - who is God himself in God, and finally through His Church, to an extend as we are able to grasp; which of course is a limited revelation, as we simply won’t be able to hold it or understand more. Jesus said so in John 16,12: I have yet many things to say to you, but you cannot bear them now.
So; we couldn’t even bear more - not even to speak of comprehending.
We simply wouldn’t be able to bear more, than what God has revealed to us anyhow. But this is so much already, that 2000 years research and explanations still leaves many clueless.
But they who simply think they are unable to understand - and even say “the world can not really comprehend” must let them being asked if they REALLY knocked - if they REALLY asked in prayer - if they REALLY in confidence and love ASKED GOD to help their disbelief. Mark 9,24: “I believe; help my unbelief!”
We and the world of course can understand - if we really want to!
Fully though, we will never understand God - neither here nor later in heaven - not even the Angels do nor ever will, as God is never knowable. But we in all our wisdom still only know a very tiny fragment of the lot God revealed about Himself.
Yet: If one keeps on with buts and ifs about God, he’ll never be given the grace to be allowed to understand. For not all are allowed to, but only those who are given the grace to believe, as they REALLY knocked - REALLY asked in prayer - REALLY in confidence and love ASKED GOD to help their disbelief. For he who knocks, will be opened. He who knocks in disbelief and convincement that there is anyhow nothing behind (this door) - he will never be heard nor opened.
So, let’s lay all our confidence in God, then we really meet God, are heard and loved.
Yours
