How do you fulfill a contract ,or law ,you do them .
Heaven and earth hasn't pass away.Why do you think the law as been done
away? Matthew 5:17-20 King James Version (KJV)
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven
: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
20 For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
6 “For I the Lord do not change; therefore you, O children of Jacob, are not consumed. 7 From the days of your fathers you have turned aside from my statutes and have not kept them.
13 “Now concerning everything which I have said to you, be on your guard; and do not mention the name of other gods, nor let them be heard from your mouth.
Matthew 4:10 New International Version (NIV)
10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.
The Narrow and Wide Gates
13 “Enter through the narrow gate.
For wide is the gate and broad is the road that leads to destruction, and many enter through it.
14 But small is the gate and narrow the road that leads to life, and only a few find it.
The Wise and Foolish Builders
24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock.
25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock.
26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand.
27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”
28 When Jesus had finished saying these things, the crowds were amazed at his teaching,
29 because he taught as one who had authority, and not as their teachers of the law.
