Was it a division of power and glory?
God gave Moses gifts so that the message that repenting, turning from serving Egypt to serving God would be beneficial, effective, powerful (I literally mean this: getting into the Promised Land is like a superhero getting in touch with the source of his powers! Israel wept when displaced to Babylon. She couldn't sing the Lord's song, in a strange land. The foreigners imported into Jerusalem were killed by lions till they learnt how to worship God. Then they too were blessed. Also remember, the Ark blessed those who were it's caretakers.).
However, those who entered Rest had to learn how to worship God: die to themselves. Every time they died to themselves, God's power was manifested, they were raised. The sign gifts were given to give additional confirmation to this message. However, the Corinthians were using the sign gifts not to glorify God, but to compete with each other. Can a person use a gift without glorifying God through weakness, through displaying dependency on God, the message? Sure, the opportunist who drove out demons in Jesus name was doing that. But his judgment would be based on whether he turned people to God or to himself, as would people like Simon the Sorcerer:
Mark 9:38
38John said to Him, “Teacher, we saw someone casting out demons in Your name, and we tried to prevent him because he was not following us.” 39But Jesus said, “Do not hinder him, for there is no one who will perform a miracle in My name, and be able soon afterward to speak evil of Me. 40“For he who is not against us is for us.
Are prosperity Gospel preachers righteous? Let's examine their actions. God's message is that if you stop serving the world and start serving Him by sharing the message, the message that serving the world resulted in a temporary solution to hunger and want, but serving God would result in treasure in heaven, as well as meeting of daily needs. Of course this results in attacks, both physical and verbal, but God raises up daily, those who pick up their cross daily. Else how could you pick up your cross daily! In addition to being able to defeat your opponents in discussions, He also gives sign gifts, like He gave to Moses, so that the listeners would know that God is with you.
What prosperity Gospel teachers do is to preach that if you plant a seed, a thousand dollars, it will be multiplied a hundred times, because we belong to a rich Father, who is testing our sincerity. Jesus came so we would be healthy, wealthy and wise!
Or rather is the power in His glory seen in the results of preaching be the more definative term?
Paul wanted to teach that the confirmation follows the message: the power, the efficacy, of weakness, expressed in picking up the Cross. The world will picks up a sword, but Christ picked up a cross, subdued His ego, gave primacy to God. The truth of the message is confirmed with the gifts, signs and wonders. At the Cross the confirmation was a literal Resurrection.
The Corinthian believers were flaunting their gifts. Without conveying the message. At the judgment, they were heading to hear the words: Depart from me you breakers of my (Christ's) law, I never knew you,
Paul would sort them out: No displaying gifts without manifesting the Cross.
Summary
This is the correct way:
Die to yourself, pick the Cross, follow Christ: share the unpopular message, confirm with signs, still be rejected, be raised up by God.
The wrong way:
Gather together, prove to others you have more and better gifts from God than others.
