Titus 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
(MY NOTE: The term "washing of regeneration" is referring to spiritual regeneration/quickening, making you alive/born again. See Vine's Bible dictionary definition below & Strong's/G3824. To be clear, the term "washing of regeneration" is not referring to water baptism. The Greek word referring to baptism is baptismos (see Vines below & Strong's #909 find references below)
Vine's Expository Dictionary of New Testament Words: Regeneration - G3824
new birth" (palin, "again," genesis, "birth"), is used of "spiritual regeneration," Titus 3:5, involving the communication of a new life, the two operating powers to produce which are "the word of truth," James 1:18; 1 Peter 1:23, and the Holy Spirit, John 3:5-John 3:6; the loutron, "the laver, the washing," is explained in Ephesians 5:26, "having cleansed it by the washing (loutron) of water with the word."
Vine's Expository Dictionary of New Testament Words: Washing
[ 1,,G909, baptismos ]
denotes the act of washing, ablution," with special reference to purification, Mark 7:4 (in some texts, Mark 7:8); Hebrews 6:2, "baptisms;" Hebrews 9:10, "washings. See BAPTISM.
[ 2,,G3067, loutron ]
"a bath, a laver" (akin to louo, See above), is used metaphorically of the Word of God, as the instrument of spiritual cleansing, Ephesians 5:26; in Titus 3:5, of "the washing of regeneration" (See REGENERATION).
(MY NOTE: Ok, so water baptism & spiritual regeneration aren't the same thing. Only Christ (Matt 3:11) can spiritually regenerate/quicken = make you spiritually alive via the spiritual baptism with His indwelling Holy Spirit.
Eph 4:5 One Lord, one faith, one baptism
(MY NOTE: 1 Lord = Jesus, 1 faith in His sin atoning sacrifice & resurrection, 1 baptism = spiritual)
1 Cor 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
(NOTE: Translators capitalized Spirit to identify deity when referring the Holy Spirit. Only Christ can baptize with His indwelling Holy Spirit.)
Col 2:11 In whom also ye are circumcised with the circumcision """made without hands""", in putting off the body of the sins of the flesh by the circumcision of Christ:
(NOTE: The baptism of the Holy Spirit is a SPIRITUAL circumcision/covenant done without hands & without water)
Deut 30:6 (A) the Lord thy God will circumcise thine heart,
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
(NOTE: Circumcision of the heart, in the spirit)
Decree
Decree (Noun and Verb) - Vine's Expository Dictionary of New Testament Words DECREE - Definition from the KJV Dictionary
Finally:
We partake in Jesus water baptism decree after our spiritual regeneration.
Emblem: a symbolic representation of a particular quality or concept.
The salvation/sealing indwelling Holy Spirit you received is a spiritual circumcision of the heart & can only be preformed thru Jesus. Done without hands & without water
Christ gave 2 commandments:
Love God 1st & love your fellow believer (Matt 22:37-40) And 2 decrees water baptism (Matt 28:19) & partaking in the Lords Supper (1 Cor 11:1-34).
Believers should be lead to partake in both Christ given decrees.
Why water baptism? You are making an outward/public statement of you're inner spiritual change. You are stating/showing your belief in Jesus death (and stating you're dying to self to live for Christ) burial (when you're immersed) & resurrection (when you rise up out of the water)
Why partake in the Lords Supper? You are making a statement that you're remembering, Christ body, that was broken for your spiritual & physical health & Jesus shed blood whereby you received remission/pardon from ALL your sins. Peace JJ
