Not Your Might, But His Spirit

"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)

No power on earth can overcome the sin of man, which has separated man from God, yet His love brings us to Him through the Spirit, and nothing can separate us from Him:

"For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord." (Romans 8: 38-39)

This love is on display for us now and forever because of what Jesus did at the Cross:

"Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins." (1 John 4: 10)

Jesus Christ did not just die for our sins -- all of them -- but He sits at the right hand of the Father justifying us every day (Romans 8: 33-34), and His blood keeps cleansing us of all our sins (1  John 1: 7).

There is nothing that we can do, because there is nothing left to be done:

"And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;" (Colossians 2: 13)

"All your trespasses." For more information on "our part", look at the binding clause of the New Covenant:

"For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more." (Hebrews 8: 12)

God will not remember our sins ever again. The New Covenant has nothing to do with us, and everything to do with His Spirit:

"And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:" (Ezekiel 11: 19)

The same Spirit writes God's laws on our hearts and minds (Hebrews 8: 10-11) and convicts us of righteousness (John 16: 8-10)

Not our might, but by His Spirit do we know, believe, and receive all things.
