Those who insist that you must obey the commands of Jesus in order to be saved/blessed/forgiven/righteous/holy are assuming that you are either
(a) a time-traveler from Israel’s distant past
(b) the devil
If you are (a), then I suggest you pick up a Sports Almanac, go back in time, and make a lot of money à la Marty McFly. Alternatively you could stick around here in the future, repent and believe the good news of God’s awesome grace, then go tell others.
If you are (b), then, um, well, er… this is awkward. I don’t really have any good news for you at all. You’ve been judged, condemned and disarmed and you have no future at all.
But if you are neither (a) nor (b) then arise, shine! For the glory of the Lord has risen upon you!
For Christ is the end of the Law [the limit at which it ceases to be, for the Law leads up to Him Who is the fulfillment of its types, and in Him the purpose which it was designed to accomplish is fulfilled. That is, the purpose of the Law is fulfilled in Him] as the means of righteousness (right relationship to God) for everyone who trusts in and adheres to and relies on Him. (Rom 10:4, AMP)
Christ has become for us wisdom from God. He is our righteousness! He is our holiness! He is our redemption! Let him who boasts, boast in the Lord!
