And you hath He quickened, who were dead in trespasses and sins. -Ephesians 2:1

But is it not said in Scripture, and do we not feel it, dear brethren, that it is the Holy Ghost who regenerates the soul? It is the Holy Ghost who quickens us. “You hath He quickened who were dead in trespasses and sins.” It is the Holy Spirit who imparts the first germ of life, convincing us of sin, of righteousness, and of judgment to come. And is it not the Holy Spirit, who, after that flame is kindled, still fans it with the breath of His mouth and keeps it alive? Its author is its preserver. Oh! can it be said that it is the Holy Ghost who strives in men’s souls; that it is the Holy Ghost who brings them into the sweet place that is called Calvary-can it be said that He does all these things, and yet is not a person? It may be said, but it must be said by fools; for he never can be a wise man who can consider these things can be done by any other than a glorious person-a divine existence.

When God first made man, He said, “Let Us make man,” not let Me, but, “Let Us make man in Our own image.” The covenant Elohim said to each other, “Let Us unitedly become the Creator of man.” So, when in ages far gone by, in eternity, They said, “Let Us save man:” it was not the Father who said, “Let Me save man, “but the three persons conjointly said, with one consent, “Let Us save man.” It is to me a source of sweet comfort to think that it is not one person of the Trinity that is engaged for my salvation; it is not simply one person of the Godhead who vows that He will redeem me; but…the three declare, unitedly, “We will save man.” ~ C.H. Spurgeon
