Deuteronomy
Chapter 11 18 "Therefore, take these words of mine into your heart and soul. Bind them at your wrist as a sign, and let them be a pendant on your forehead. 26 "I set before you here, this day, a blessing and a curse: 27 a blessing for obeying the commandments of the LORD, your God, which I enjoin on you today; 28 a curse if you do not obey the commandments of the LORD, your God, but turn aside from the way I ordain for you today, to follow other gods, whom you have not known.

Romans
Chapter 3 21 1 But now 2 the righteousness of God has been manifested apart from the law, though testified to by the law and the prophets, 22 the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction; 23 all have sinned and are deprived of the glory of God. 24 They are justified freely by his grace through the redemption in Christ Jesus, 25 whom God set forth as an expiation, 3 through faith, by his blood, to prove his righteousness because of the forgiveness of sins previously committed, 28 For we consider that a person is justified by faith apart from works of the law.

Matthew
Chapter 7 21 "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, 1 but only the one who does the will of my Father in heaven. 22 Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name? Did we not drive out demons in your name? Did we not do mighty deeds in your name?' 23 Then I will declare to them solemnly, 'I never knew you. 2 Depart from me, you evildoers.' 24 3 "Everyone who listens to these words of mine and acts on them will be like a wise man who built his house on rock. 25 The rain fell, the floods came, and the winds blew and buffeted the house. But it did not collapse; it had been set solidly on rock. 26 And everyone who listens to these words of mine but does not act on them will be like a fool who built his house on sand. 27 The rain fell, the floods came, and the winds blew and buffeted the house. And it collapsed and was completely ruined."

"Reprogram your heart and soul with My new Operating Instructions.  Wear them on your mind and wrists (thinking and working.  Also, this is a remarkably different sign from Rev 13, where the Mark of the beast is on the right hand and forehead.)  "You have free will to choose what I set before you, obedience and blessing (Heaven), or disobedience and curse (Eternity in agony).  You will be cursed if you follow other Operating Instructions with different Programs whom you've not known."  (Do not think "newness" offers validity)

The Programmer has opened a new route to access Him. First, there was the Law, but now, we can access Him through Jesus Christ, (The living, loving Program who took human form so that we could download Him in the Eucharist.) for all who believe. 

Since all of us have disobeyed the Operating Instructions, we should all be deprived of the glory of The Programmer.  But Jesus, by His Grace, has allowed us to (continually) access The Programmer through Him.  God sent Him as a sacrifice of His Blood, a sign of forgiveness to prove that His love was greater than our sin or the power that caused it.  We are justified by faith in Him (and, His faith in us) apart from obeying laws.

"Just calling me 'Lord, Lord' is not enough for everyone to be saved, but only the one who obeys the Operating Instructions provided by The Programmer will enter.  Many will tell Me at Judgment, 'Lord, Lord, didn't we prophesy in Your Name?  Didn't we drive out demons in Your Name?  Didn't we do mighty deeds in Your Name'  Then, I will solemnly tell them, 'I never knew you.  Depart from me, you doers of evil.'

"Everyone who listens to My Instructions and acts on them will be building his house on rock.  The inevitable attempts to destroy it will not succeed because it was solidly set on rock.  Those who listen to me but don't act on them is like a fool who builds on sand.  The rain, floods, and wind will completely ruin it."

(My Words are The Program.  No force on earth can overpower it.)
