Equality & Priority

When I read this morning about the proclamation of the Gospel,first to Jews then to Gentiles, it's the Lord's sequence in this proclamation.

And I then read the reward & punishment from the Lord upon those who seek Him,first also to Jews then to Gentiles,again there's a priority here.

In terms of both the Gospel and the reward to Jews then to Gentiles,Paul said that for God does not show any favoritism.

There's a problem arising here.
No favoritism means God is impartial and would have no bias towards man. But in reality there's always a first and an after. With God it's no unequality, but with us there might probably be unequality with this.

How are we getting close to God's way in it ?
Equality means impartiality but doesn't mean no priority. Jesus specially brought along Peter,James and John with Him in His Mount Transfiguration just shows this.

With men equality might mean evenness,sameness and no difference.
With God,equality might mean priority,sequence and His choice.

It 's not our way to understand His impartiality.
