Truly I tell you,” Jesus replied, “no one who has left home or brothers or sisters or mother or father or children or fields for me and the gospel will fail to receive a hundred times as much in this present age: homes, brothers, sisters, mothers, children and fields—along with persecutions—and in the age to come eternal life. But many who are first will be last, and the last first.

Mark 10:29-31 NIV

Jesus called us to forsake all (Luke 14:33), and yet promises our needs will be met from above (Matthew 6:33).  This parodox underscores the nature of the Kingdom.  It is not of this world (John 18:36), but it is all sufficient to meet every need (Philippians 4:19).

Jesus said,

And why are you worried about clothing? Observe how the lilies of the field grow; they do not toil nor do they spin,  yet I say to you that not even Solomon in all his glory clothed himself like one of these. But if God so clothes the grass of the field, which is alive today and tomorrow is thrown into the furnace, will He not much more clothe you? You of little faith!

Matthew 6:28-30 NASB

It is not by justice that we recieve, but by grace.  No matter the trial, no matter the test, and no matter the persecution, as Mark 10:30 denotes, the reward we receive is based on nothing but Grace and Mercy.

This is the essential difference between the world and faith.

God has all we need.  He amply supplies our every requirement.  And, yet, it is not as a reward, or in repayment for what was lost or stolen.

God is just.  Those who forgive will be forgiven, and those who are forgiven have access to the Grace of God.  When we enter into an expectation for our service, or look to receive the hundred fold of Mark 10 on the basis of our efforts, endurance, or self, we miss the point.

Rather, it is as we lay them down, live free, even in the face of it, that we are utterly free from it, and God commands His blessing upon us.

Thus, the Kingdom is separate, free, from the constrains of this world.
