the tax collectors and the prostitutes will enter the kingdom of God before you do

Here "kingdom of God" refers to God's rule as king. Alternate translation: "when God establishes his rule on earth, he will agree to bless the tax collectors and prostitutes by ruling over them before he agrees to do that for you" (See: rc://en/ta/man/translate/figs-metonymy)
