John Wesley on Isaiah 54:10

The mountains - Shall sooner depart from their places than any kindness shall depart from thee. The covenant - That covenant whereby I have made peace and friendship with thee, and have promised to thee all manner of happiness. God will not cast off his Christian church, as he cast off the church of the Jews, the New covenant is established upon better and surer promises than the Old. The Lord - Who doth this not for thine own merits, but merely for his own grace and mercy.
