Your conception of God, defines yr relationship, expectation and attitude towards God in particular and mankind in general.
If one were to believe that God could call for a conclave of angels/spirits and give the liberty to one to be a lying spirit in the mouths of prophets- like what Micaiah (1kings 22: 22) said, it is questioning the sovereignty of God.
God Himself may not do this to his children, but when he finds that his children have exceeded in wickedness thru willfulness than weakness, He could resort to any sovereign device. But He never uses these against the humble ones before God! God’s will be done. Period.
