All through the Torah, we see commandments for BATHING to rid one of uncleanness. Leviticus 15, 16, 17 and Numbers 19 all contain references for a ritual purification by bathing in water. Entrance into the Tabernacle and/or Temple could not occur unless this bathing was done.
When Yochanan the Immerser thundered onto the scene, demanding the Talmud-laden Hebrews to forsake their sin and return to the Torah, bathing to SPIRITUALLY CLEANSE AND RENEW oneself was very familiar to Israel.
This act of immersion to cleanse oneself of impurity -- a literal commandment found in Torah, continues to be applied literally today -- although without a Temple the only way this commandment can be applied is our declaration of obedience to YahShua.
Almost the entire Christian church has no problem taking the commandment of immersion literally -- baptism -- yet they want to make physical circumcision a spiritual metaphor! Certainly immersion has deep spiritual significance, yet no Christian would say a man could knowingly reject water baptism and be “fine with the Lord”.
If Christians want to be consistent with their Plato-based theology of spiritualizing away the commandments of Torah -- they should stop baptism IMMEDIATELY!
