For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the Lord that hath mercy on thee. (Isaiah 54:10)
One of the most delightful qualities of divine love is its abiding character. The pillars of the earth may be moved out of their places, but the kindness and the covenant of our merciful Jehovah never depart from His people. How happy my soul feels in a firm belief of this inspired declaration! The year is almost over, and the years of my life are growing few, but time does not change my Lord. New lamps are taking the place of the old; perpetual change is on all things, but our Lord is the same. Force over turns the hills, but no conceivable power can affect the eternal God. Nothing in the past, the present, or the future can cause Jehovah to be unkind to me.
My soul, rest in the eternal kindness of the Lord, who treats thee as one near of kin. Remember also the everlasting covenant. God is ever mindful of it—see that thou art mindful of it too. In Christ Jesus the glorious God has pledged Himself to thee to be thy God and to hold thee as one of His people. Kindness and covenant-dwell on these words as sure and lasting things which eternity itself shall not take from thee.
