I have seen their ways, but I will heal them;
    I will guide them and restore comfort to Israel’s mourners,
19     creating praise on their lips.
Peace, peace, to those far and near,’
    says the Lord. ‘And I will heal them.’
20 But the wicked are like the tossing sea,
    which cannot rest,
    whose waves cast up mire and mud.
21 ‘There is no peace,’ says my God, ‘for the wicked.’

In the New Testament, Paul takes up these words in which God is speaking, and He applies them to Jesus:

” He came and preached peace to you who were far away and peace to those who were near. For through him we both have access to the Father by one Spirit.” (Eph.2:17,18).

Jesus ”came” in and through His church to those ”far away” (the Gentiles), and to those who were ”near” (the Jews) and He ”preached peace” to them: the possibility of ”access to the Father”, and mended relationships with each other.

If you look back in that chapter to verse 14, you see that Jesus ”himself” is the peace He proclaims. Only in Him can sinful people know reconciliation with God, and divided people be drawn into harmonious relationships with one another.

But what will you do with Jesus? He comes to you and preaches peace, but you (we) can reject His preaching.
