People's existence is permanently validated as we're created by and in the image of God. There's no higher validation.
Science can't find or reason definite purpose for our existence when they remove God. They resort to chaos and random chance to assign some semblance of meaning.
God questions us so that we can begin to think and align those thoughts willingly with his will.
His will?
we are already preset by God, he knows everything we say and do, I have already said he would never need to say anything to us, he knows about every single cell and molecule in our body, he knows how they are arranged, he can realign them any time he likes, he can do ANYTHING.
He doesnt ned to lead us anywhere, he knows were we are going from before we are even created.
