Nice deflect SG with the whole "you believe in a big devil and little God". I agree that we, the elect, are conquerors and can resist satan due to him being bound by the work of the cross. All of your verses are very clear on that. No disagreement with that. The gospel continues to spread, people continue to come to Christ, and church continues to grow and conquer to this day. "of the increase of His government, there is no end".
But you are not addressing how satan has the following abilities while being bound:
a.) signs and wonders by false prophets to possibly deceive the elect associated with the destruction of Jerusalem in the 1st century
Matthew 24:24-25 For false Christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible. See, I have told you in advance.
b.) Satan prowling around looking to devour someone
1 peter 5:8 Be sober-minded and alert. Your adversary the devil prowls around like a roaring lion, seeking someone to devour
c.) Apostasy due to the antichrist in the 1st century
1 John 2:18-19 Children, it is the last hour; and just as you have heard that the antichrist is coming, so now many antichrists have appeared. This is how we know it is the last hour. They went out from us, but they did not belong to us. For if they had belonged to us, they would have remained with us. But their departure made it clear that none of them belonged to us.
d.) Satan disguising himself as an angel of light in order to deceive.
2 Corinthians 11:14 And no wonder, for even Satan disguises himself as an angel of light. So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds.
e.) Satan is loosed to persecute the church upon Christ's ascension
Revelation 12:12 Therefore, rejoice, O heavens and you who dwell in them! But woe to you, O earth and sea, for the devil has come down to you in great wrath, because he knows that his time is short!”
Revelation 12:17 Then the dragon became furious with the woman and went off to make war on the rest of her offspring, on those who keep the commandments of God and hold to the testimony of Jesus.
Acts 14:2-5 But the unbelieving Jews stirred up the Gentiles and poisoned their minds against the brothers. So they remained for a long time, speaking boldly for the Lord, who bore witness to the word of his grace, granting signs and wonders to be done by their hands. But the people of the city were divided; some sided with the Jews and some with the apostles. When an attempt was made by both Gentiles and Jews, with their rulers, to mistreat them and to stone them,
Acts 8:1 And Saul was there, giving approval to Stephen’s death. On that day a great persecution broke out against the church in Jerusalem, and all except the apostles were scattered throughout Judea and Samaria.
f.) satan had a throne on earth in the 1st century
Revelation 2:13 I know where you live, where the throne of Satan sits.
g.) Satan had blinded the minds of unbelievers in Paul's time.
2 corinthians 4:4 the god of this age has blinded the minds of unbelievers so they cannot see the light of the gospel of the glory of Christ, who is the image of God.
h.) Satan's work in the sons of disobedience in the 1st century
Ephesians 2:2 in which you used to walk when you conformed to the ways of this world and of the ruler of the power of the air, the spirit who is now at work in the sons of disobedience
My belief is that the loosing of satan is not that satan's kingdom grows, but serves a purpose in God's will for refining the elect, while those that are not elect take part in apostasy.
Romans 4:3-5 Not only that, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out His love into our hearts through the Holy Spirit, whom He has given us
John 14:30 I will not speak with you much longer,
for the prince of this world is coming,
and he has no claim on Me.
