Do All Things Through His Spirit of Grace

"Then he answered and spake unto me, saying, This is the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts." (Zechariah 4: 6)

What "Spirit" does Zechariah speak of in this verse? He explains later in his prophecies:

"And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn." (Zechariah 12: 10)

Every person who believes on Jesus Christ has been adopted into the family of God:

"That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel" (Ephesians 3: 6)

So, because we are in Christ (Galatians 3: 29), then we are of the house of David, and we belong to the New Jerusalem, too (Galatians 4: 26).

This Spirit of Grace is accorded to all of us because of what Jesus Christ did for us at the Cross:

"Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear." (Acts 2: 33)

We do all things by the Spirit of God working in us:

"But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will." (1 Corinthians 12: 11)

and

"Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;" (Titus 3: 5)

It is the grace of God which makes us who we are, and which gives us the power to all things which God wills within us to do (Philippians 2:12-13):

"But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me." (1 Corinthians 15: 10)

Let His Spirit work within you, and thus through Christ, you can do all things (Philippians 4: 13)
