Those who try to pit Jesus against Paul are scriptural newbs. They usually say things like,"Jesus' message was the Kingdom of God, and Paul's was all about Jesus." Silly, silly, silly!!!!
Paul says,"Do you not know that the wicked will not inherit the kingdom of God?" (1 Cor.6:9)
Jesus says," Some who are standing here will not taste death before they see the Son of Man coming in HIS KINGDOM." (Mt.16:28)
Paul says,"I warn you, as I did before, that those who live like this will not inherit the kingdom of God." (Gal.5:21)
Jesus says," The son of Man will send out his angels, and they will weed out of HIS KINGDOM everything that causes sin and all who do evil." (Mt.13:41)
Paul says,"For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit." (Rom.14:17)
Jesus says," All things have been committed to ME by my Father." (Lk.10:22a)
By these verses you may see that Paul often spoke of the kingdom of God, and Jesus often spoke of Himself. There is no either/or rule here. Those who say otherwise are eisegetes.
