Charles H. Spurgeon wrote, "We do not know Christ as our Savior until the Holy Spirit is put within us. Our Lord says, 'He shall receive of mine, and shall show it unto you' (John 16:14). You never personally know the Lord Jesus, until the Holy Spirit makes him known to you."
God says, "I will put my Spirit within you" (Ezekiel 36:27). The Holy Spirit is within all who believe, that we may know the reality of the living Christ. The Holy Spirit does many things in the lives of believers, but first and foremost, he enables you to know Christ as Savior.
The Holy Spirit enables you to know Christ as Savior through the gospel (1 Corinthians 15:1-4). The message of the gospel is meaningless to those who believe not (1 Corinthians 2:14). But, to all who are taught by the Holy Spirit, the gospel of Christ is the power of God unto salvation (Romans 1:16; 1 Thess. 1:5).
The same Holy Spirit who raised Jesus our Lord from the dead is the same Holy Spirit who quickens you to know new life in Christ (Romans 1:4; Ephesians 2:1). He must convict and convince you to believe in Christ as your Savior (John 16:7-11).
The Holy Spirit enables you to know Christ as your Savior through the Scripture. That's the reason Jesus spoke of the Holy Spirit, saying, "He shall receive of mine, and shall show it unto you." He renews your heart and mind to know the truth of Christ, according to the Scripture (1 Corinthians 15:1-4).
