Is water baptism necessary for salvation? I'm baptized but Mark 16:16 seems unbiblical, but yet it's in the Bible?
(1) "Whoever believes and is baptized will be saved" (Mark 16:16a).
(2) "but whoever does not believe will be condemned" (Mark 16:16b; cf. John 3:18).
Notice what is missing above. Mark 16:16 does not say anything about genuine believers who have not been baptized - like the unbaptized thief on the cross next to Jesus; "Truly, I say to you, today you will be with me in paradise" (Luke 23:43). This one thief went to paradise on the very same day he was saved and physically died without being baptized! This by itself disproves the false "works" doctrine of baptismal regeneration. Mark 16:16 does not say, 'He who is not baptized will be condemned.' Why? Because the one requirement for salvation is mentioned in Mark 16:16b, that is, "whoever does not believe will be condemned."
So, Mark teaches that there is one requirement for salvation - the God given gift of "belief" (Mark 11:22; John 3:16, 36; 5:24; 8:24; 16:31; Acts 16:31; Rom. 5:1; Phil. 3:9, et. al.); whosoever believes shall be saved and whosoever does not believe shall be condemned (John 3:18). This is consistent with the remainder of Scripture. O.T. Abraham was saved by faith alone (Rom. 4:1-25; Gal. 3:6-22; see Heb. 11 for an incomplete list of O.T. saved saints). Cornelius was saved by faith "before" he was baptized (Acts 10:44-48). Paul told the adult jailer in Acts 16, "Believe in the Lord Jesus, and you will be saved" (Acts 16:31). Note that Paul did not add another requirement! Only "after" the adult jailer was saved was he baptized (Acts 16:33). So, good works - including the good work of water baptism - follow salvation (Eph. 2:10).
Therefore, assuming that Hagar was with child soon after Abraham's faith (Gen. 15:6), there is a space of at least 14 years between Abraham being reckoned to be righteousness and him being circumcised. While it may have even been longer; a time less than 14 years is literally impossible. So, uncircumcised Abraham was declared a righteous man well before he received the covenant sign and seal of circumcision.
- Genesis 15:2-3, states Abram was childless; "for I continue childless" ... "Behold, you have given me no offspring."
- Genesis 15:4-6, chronicles the promise to Abram that he would have an heir; "your very own son shall be your heir."
- Genesis 16:16, reports that, "Abram was eighty-six years old when Hagar bore Ishmael" to him.
- Genesis 17:24-27, affirms that Ishmael was 13 yoa when his 99-year-old father Abraham, and his whole household were circumcised.
In my opinion, in the Gospel of Mark "obedience" to the covenant sign and seal of baptism is being emphasized because Mark's audience is primarily Gentile, who weren't as familiar with the importance of the covenant signs and seals as the Jews were. In the O.C., we observe something related. Zipporah - Moses' wife (Exod. 3:1), a Gentile, a Midianite - by God's grace "obeyed" when God said to circumcise her son (cf. Exod. 4:25). By the same grace, Mark - even if someone added to his Gospel - emphasized the "obedience" of the N.C. sign and seal of baptism in Mark 16:16 to his primary Gentile audience. Abraham was a Gentile from the Ur of the Chaldees (Gen. 11:31). Gentiles being in the eternal covenant was also emphasized in the Abrahamic Covenant - "father of many nations" (Gen. 17:4); it's emphasized throughout Scripture (Psa. 45:17; Isa. 42:6: Zech. 14:16; Eph. 3:1-6, etc.).
Baptism is a command of our Lord Himself (cf. Matt. 28:19). It is extremely important as a covenant sign and seal. The Apostle Paul informs us in Romans 4:11 that circumcision, and thus baptism (Col. 2:8-15), is a "sign." Ultimately signs point to something greater, grander, and more important themselves. As was circumcision in the O.C., baptism in the N.C. is a sign that one is a member of God's eternal covenant. As such, all the blessings and cursings are in effect for each and every person (child and adult) in the covenant.
Moreover, baptism signifies regeneration and the repentance of sins (John 3:5; Acts 2:38). Regeneration is the work of the Holy Spirit alone (John 3:1-8). Clearly, faith and repentance are gifts of God (Eph. 2:8-9; 2 Tim. 2:24-26) and His work alone in the believer, whereas baptism is the work of the Spirit and man. Water baptism symbolizes the new life of the Holy Spirit in the believer. Moreover, its washing represents the cleansing from sin that results from faith in the Lord Jesus Christ (cf. 1 Pet. 3:20-21). One is pure in Christ alone!
Under both covenants - the N.C. is the re-newed covenant (see below) - infants are covenant members too (1 Cor. 7:14: cf. lost people can be in the covenant too - circumcised Esau and Ishmael) and as such are responsible to abide by all the terms of the covenant - including in time having saving faith in Jesus Christ alone for salvation. As the WCF Chapter XXVIII, Of Baptism, IV states:
The efficacy of Baptism is not tied to that moment of time wherein it is administered; yet, notwithstanding, by the right use of this ordinance, the grace promised is not only offered, but really exhibited, and conferred, by the Holy Ghost, to such (whether of age or infants) as that grace belongs unto, according to the counsel of God's own will, in His appointed time.
Covenant infants should be baptized. See links below.
