Wow the blessing of those loving peace, because sons of God they will be called.
It would seem as though it is easier for mankind to make war that it is to make peace. It is said that there are only eleven countries in the world that are not involved in some kind of conflict.
The world needs peacemakers, and Jesus said that they will be called the sons of God.
The word for peacemakers is:
It occurs only once in the New Testament, although there is a combination of words in James 3.18 meanings ‘peace makers’:
And those who are peacemakers will plant seeds of peace and reap a harvest of goodness – (NLT).
In the context James states that being a peacemaker comes from the wisdom that comes from Heaven, therefore, it comes from God:
 But the wisdom that comes from heaven is first of all pure. It is also peace loving, gentle at all times, and willing to yield to others. It is full of mercy and good deeds. It shows no partiality and is always sincere – James 3.17 (NLT).
Therefore, to be a peace keeper it is essential to be born again, filled with the Holy Spirit and living a righteous life.
There is another related word in Colossians 1.20:
 and by Him God reconciled everything to Himself. He made peace with everything in heaven and on earth by means of His blood on the cross (NLT).
God is the supreme peace maker. What Paul is saying is that God has made peace where there was no peace. We were so far away from God; indeed we were the enemies of God.
This means that we sinners had no way of bringing peace between God and ourselves.
The lost sheep was unable to find its own way home. It was lost. It had no compass to find its way back to the sheep fold.
This is why the shepherd set out to find it, knowing that the only way that sheep was going to be saved was by his going out to find it.
Jesus has done that for us by shedding His blood on the cross and making peace between God and us.
Writing to the Romans Paul put it this way:
Therefore, since we have been made right in God’s sight by faith, we have peace with God because of what Jesus Christ our Lord has done for us – Romans 5.1(NLT).
