God has clearly communicated to us His will concerning all men in 1 Timothy 2:4
God, our savior, Who wills all mankind to be saved, and to come into a realization of the truth. For there is one God, and one mediator, also between God and mankind, amen, Christ Jesus, who is giving himself a correspond ransom for all (the testimony in its own eras)
A few verses earlier, it says,
faithful is the saying and worthy of all welcome, that Christ Jesus came in the world to save sinners, foremost of whom I am. 1 Timothy 1:15
Since this is God's will, then we are praying accordingly for all mankind, that even includes kings and those who are in authority so that we can live a mild and quiet life.
That means that our hearts are praying for those who might be oppressing us, it keeps our hearts from getting angry and bitter towards them, and keeps the attitude of God in our hearts towards all mankind which in this era is one of conciliation.
So how does that align with these vessels that are adapted for destruction?
Now, if God, wanting to display His indignation, and to make His power known, carries on, with much patience, the vessels of indignation adapted for destruction, it is that he should also make known the riches of his glory on the vessels of mercy...
First of all, you have to read the whole
context of who Paul is talking about here. This has to do with the nations and especially Israel at this particular point in time. Jesus Christ had came onto his own people who totally rejected Him and crucified him. They were given another chance to have the kingdom come in if the whole nation repented and accepted Jesus Christ as their Messiah. God had shown much patience towards them. They did not and so now God has adapted ( made suitable for a new use or purpose) them for destruction instead of salvation. We know the history what happened in 70 A.D. and since the nation, as a whole has been deemed no longer His people. Of course, right after that, we see the quote from Hosea in 25:23. It is that concerned with Israel.
God, in His sovereign mercy, will reverse the sentence which He pronounced against them. In the very same place in which they were named "Lo-ammi", there they shall be called sons of the living God. Concordant commentary.
