Trimming and cutting down trees for an elderly widow.
When using a chainsaw, one important thing needed is bar oil; this oil is distributed to the blade as the saw runs to keep things smooth. If the oil is not used, it can cause irreparable damage to the blade.
The same thing is true of the Christian life without the Holy Spirit. Oil in The Bible is often used to symbolize the Holy Spirit. For example, in the tabernacle “oil [was used] for the light,” and more specifically God wanted “pure olive oil beaten for the light, to cause the lamp to burn always.” The lamp is in reference to the seven-fold lampstand which was in the holy place, which represents Jesus, “the Light of the World,” who, through The Holy Spirit’s power/indwelling, uses us to be lights. We see this in Revelation, where Jesus, in High Priestly garments, tends to our flames,
"And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle… …The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches." [Rev 1:13; 20]
Just as the oil is the fuel for the light of the lampstand, so too The Holy Spirit is the fuel for our “fire” or “light.” And just as the chainsaw blade will break without oil, so too our light will be quenched without The Holy Spirit. As Paul warns, “Quench not the Spirit.”
We must be diligent to not quench Him, neither to grieve Him with continued sin; as Paul writes again,
"And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption." [Eph 4:30]
"Let your loins be girded about, and your lights burning." [Lk 12:35]
So let us be like the wise virgins who in their waiting for the wedding, were wise and “took oil in their vessels with their lamps.” [Mt 25:4] This is something we are commanded to do: to be being filled with The Holy Spirit always; that is, receiving from Jesus new fillings of His Spirit each day just as the tabernacle lampstand would. We read in Ephesians,
"And be not drunk with wine, wherein is excess; but be being filled with the Spirit; Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord; Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ; Submitting yourselves one to another in the fear of God." [Eph 5:18-21]
And Jesus, who tells us,
"And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask an egg, will he offer him a scorpion? If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?" [Lk 11:9-13]
