For to be carnally minded is death; but to be spiritually minded is life and peace. – Romans 8:6
Christ is our life, but He works in us through His Holy Spirit, who dwelleth in us evermore. We know that this life very much consists in union with God. “For to be carnally minded is death; but to be spiritually minded is life and peace. Because the carnal mind is enmity against God: for it is not subject to the law of God, neither again can be. So then, they that are in the flesh cannot please God.” Death as to the body consists in the body being separated from the soul; the death of the soul lies mainly in the soul’s being separated from its God. For the soul to be in union with God is the soul’s highest life; in His presence it unfolds itself like an opening flower; away from Him it pines, and loses all its beauty and excellence, till it is as a thing destroyed. Let the soul obey God, let it be holy, pure, gracious, then is it happy and truly living; but a soul sundered from God is a soul blasted, killed, destroyed; it exists in a dreadful death; all its true peace, dignity, and glory, are gone; it is a hideous ruin, the mere corpse of manhood. The new life brings us near to God, makes us think of Him, makes us love Him, and ultimately makes us like Him. My brethren, it is in proportion as you get near to God that you enter into the full enjoyment of life-that life which Jesus Christ gives you, and which Jesus Christ preserves in you. “In His favour is life.” Psa 30:5 “The fear of the Lord is a fountain of life.” Pro 14:27 To turn to God is “repentance unto life.” To forget God is for a man to be “dead whilst he liveth.” To believe the witness of God is to possess the faith which overcometh the world. “He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made Him a liar, because he believeth not the record that God gave of His Son. And this is the record, that God hath given to us eternal life, and this life is in His Son. He that hath the Son hath life; and he that hath not the Son of God hath not life.” ~ C.H. Spurgeon
