Rom 6:15 What then? shall we sin, because we are not under the law, but under grace? God forbid. Rom 6:16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness? Rom 6:17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you. Rom 6:18 Being then made free from sin, ye became the servants of righteousness
1Co 9:21 To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law.
1Co 10:1 For I do not wish you to be ignorant, brothers, that all our fathers were under the cloud, and all passed through the sea, 1Co 10:2 and all were immersed into Mosheh in the cloud and in the sea, 1Co 10:3 and all ate the same spiritual food, 1Co 10:4 and all drank the same spiritual drink. For they drank of that spiritual Rock that followed, and the Rock was Messiah
Gal 3:13 Messiah redeemed us from the curse(penalty of death) of the Torah, having become a curse for us 14 in order that the blessing of Abraham might come upon the nations in Messiah Yeshua
Dt 11:26 Behold, I set before you this day a blessing and a curse; 27 A blessing, if ye obey the commandments of the LORD your God, which I command you this day: 28 And a curse, if ye will not obey the commandments of the LORD your God, but turn aside out of the way which I command you this day
Circumcision...it is not about salvation, it is about blessing that comes from obedience for according to Paul, obedience IS righteousness and we are all to run the race of righteousness for if the works are of the heart, the works are not of us but of the Spirit that resides in our hearts. The same Spirit that circumcised our hearts in order that the sin of the flesh no longer dulls HIS Light of righteouness that HE planted in us when we accepted HIM into our heart. Therefore, the works that come of the heart is God's Light to the world because those works are HIS, not ours. We are HIS servants, created for the sole puprose to serve HIM as HE instructs.
