You might as well try to hear without ears or breathe without lungs, as to try to live a Christian life without the Spirit of God in your heart. - D.L. Moody
Quench not the Spirit - (I Thes 5:19) This language is taken from the way of putting out a fire, and the sense is, we are not to extinguish the influences of the Holy Spirit in our hearts. Possibly there may be an allusion here to fire on an altar, which was to be kept constantly burning. This fire may have been regarded as emblematic of devotion, and as denoting that devotion was never to become extinct. The Holy Spirit is the source of true devotion, and hence the enkindlings of piety in the heart, by the Spirit, are never to be quenched. Fire may be put out by pouring on water; or by covering it with any incombustible substance; or by neglecting to supply fuel. If it is to be made to burn, it must be nourished with proper care and attention. The Holy Spirit, in his influences on the soul, is here compared with fire that might be made to burn more intensely, or that might be extinguished. (Selected)
