The Apostle Paul is alluding to the true worth of the believer having the capacity and ability to make judgments in the future. As such, he is worthy even now to be a judge in an matter of disputes among God’s people. There is the leadership of the church that should be able to help resolve differences between brethren. And for the gravity of the matter at hand, the Apostle Paul is confident that the believer with the indwelling Holy Spirit and the counsel of God’s Word would have the ability to resolve differences between brethren.
