"The mountains shall depart but my kindness and My covenant of peace shall not depart form you". Isaiah 54:10.
Mountain denote strength: your earthly strength may fail. The people whom you have trusted might have forsaken you because human love is fickle and wobbly at its best and is selfish. God's love is unselfish and seeks your benefit. God loves by choice therefore Hi is never moved. Fear not, He will deliver, strengthen and establish you!!!
