My point of view about the necessity of exactly as much sin and evil as God actually allows is best summed up by Ray Prinzing, especially the fifth paragraph.
TIME, ETERNITY AND GOD – REDEMPTION’S GLORY – RAY PRINZING
“Modern theology has so long circumvented our thinking and teaching to the biased idea that God will save only part of His creation and so limited His redemptive powers that we have forgotten that with God all things are possible and shall be wrought out in due time. God has a definite schedule for saving His creatures, and there is nothing that can withstand His purpose.
Sin was allowed for wise ends, and only after these have been secured will sin cease to exist. It is all a part of God’s purpose of the ages and redemption’s glory will only shine out the more after the plan’s execution. God never allows sin to go beyond His transforming power. God always has everything under perfect control.”
“ ‘And we have seen and do testify that the Father sent the Son to be THE SAVIOUR OF THE WORLD.” 1John 4:14.
‘Who will have ALL MEN to be saved, and to come into a knowledge of the truth’ 1Tim. 2:4.
This is not a pitting of man’s will against the will of God as some try to teach, with man’s will able to resist and hold out until God cannot change him, but must throw him into some eternal cesspool to be tormented. NAY – for we read that ‘He is working out all things after the counsel of His own will,’ and man cannot disannul that which HE has willed. It is God’s will that all shall come to Christ. He is the propitiation for the sins of the WHOLE WORLD. Why then shall we be so foolish as to dispute the immutability of His truth?”
“God is sovereign, and He controls all the interaction of evil and good, and causes all to redound to His own glory. It is not – what was lost by the fall was to be regained by redemption, BUT by the interaction of FALL AND REDEMPTION, God achieves greater, wiser, nobler, and higher goals for everyone than by the Adamic race remaining in its pristine state.
Evil and good are synchronized to accomplish God’s will and purpose, so that the ultimate goal shall reveal all evil transformed back into good, and all negation cancelled out by GOOD. Evil is allowed for wise ends, and when these are secured it must cease to exist, for God will restore all things into good. HE controls all the interaction between evil and good until His purpose of the ages is fulfilled. Then shall God be All in all.”
“We would not minimize the judgments of God, but the more the spirit of revelation unfolds the truth, the more we see God’s judgments in proper perspective, that they are remedial, corrective in their nature and used to bring forth a state of righteousness. They shall not be executed in unholy vengeance, for MERCY shall balance the score. God’s judgments are ever tempered with mercy, and when they have fulfilled their purpose, the judgments end. Mercy will outlast all the judgments, and will rejoice in the ultimate restoration of all that was perverted, corrupt, and evil.
Mercy can operate on the basis of justice because Christ has gathered the whole into His own heart, and suffered to reconcile all to Himself.”
