We, who believe in Jesus Christ, have been saved through God’s mercy. We have been cleansed, sanctified, and justified in and through Jesus, our Savior.
He saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit. (Tit 3:5 NIV)
The indwelling Holy Spirit is constantly cleansing us and renewing our minds. One tool that is helpful is the Word of God.
And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God. (1 Cor 6:11)
. . . that he might sanctify her [the Church], having cleansed her by the washing of water with the word . . . (Eph 5:26 ESV, words in brackets added) Another way that we are continuously cleansed and sanctified is through a daily reading of the Scriptures as well as constant meditation upon them. This is what we may choose to do in order to cooperate with the Holy Spirit, our teacher.
. . . knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified. (Gal 2:16) This Bible verse reiterates the truth that no one is justified by fulfilling the law but rather through an ongoing faith in and relationship with Jesus Christ, the Savior of mankind. Praise God!
