"In mercy the throne will be established." What the heck does that mean?

Ran across this Scripture today and I think it is a good opportunity to discuss what some may see as a contradiction.

Isaiah 16:5(NKJV)

5    In mercy the throne will be established;     And One will sit on it in truth, in the tabernacle of David,     Judging and seeking justice and hastening righteousness.”

Let's look at the first line.  In mercy the throne will be established.  I think that there are many who think that mercy is automatic and that it automatically precludes judgment or punishment.   In my opinion, nothing could be further from the truth. 

Now I believe the throne being established refers to Jesus' kingdom here on earth.  Let's look at the rest of the passage.  It tells us that once the throne is established Jesus will be judging and seeking justice.

The judging part should come as no surprise.  We are told many times in Scripture that Jesus will come back to judge the living and the dead.

2 Timothy 4:1-2(NKJV)

1I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead £at His appearing and His kingdom: 

2Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. 

But what about the justice part?  Well remember that Jesus and God are always in agreement.  Therefore some blood has to be shed for the sins committed for justice to be served.  That is God's rule. 

Now we all have a choice to make.  We can pay that price with our blood or with the blood of Jesus, it is our choice, but either way it requires a blood payment.

I know there will be many that ask "where is the mercy thing?".  Where is the mercy if I am still being judged?

The mercy is in the fact that God gives you the choice of believing in Jesus or not.  The mercy is in the fact that you get total control in deciding whether to pay the blood debt with your blood or with the blood of Jesus. 

Mercy has to be accepted just like salvation because in the end, salvation is the only mercy that counts.  For those who reject Jesus, they are rejecting God's mercy. 

It's not that mercy wasn't offered.  It is that many chose to reject that mercy.  Make sense?
