Ephesians 6:1-3 for starters (quoting Exodus 20 and Deut. 5). So this one was not "nailed to the Cross" and declared obsolete.....nor were any of the others that Paul elaborates on in his epistles, such as admonitions against lying, stealing, murder, covetousness, idolatry, adultery, etc. (see Ephesians 4, 5; Gal. 5; Col. 3). The commandments of God are reiterated throughout the epistles (as well as in the Gospels and Acts). Sabbaths and holy days ARE (not were) a shadow (type) of things to come (Col. 2:16).

Keeping Torah is simply keeping the wise instructions/precepts of God. All Scripture is given by inspiration of God and is profitable for....instruction in righteousness. (2 Tim. 3:16).
