"Without the work and authority and the power of the Holy Spirit there would never be a single believer in our Lord and Saviour Jesus Christ."
This is "Good News", salvation is completely of the Lord, from start to finish. We are only recipients of His Grace and Mercy. He saves us, He keeps us and He will bring us into His Glory for Christ's sake.
Tit 3:5 He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit,
Tit 3:6 whom He poured out upon us richly through Jesus Christ our Savior,
Tit 3:7 so that being justified by His grace we would be made heirs according to the hope of eternal life.
