When people say that Christianity is about relationship, they are correct. God created human beings in His image. He could have created robots or fleshly automatons, but instead He created human beings.
In the OT, this was not always clear. However, there are those who will claim that love is something new in the NT. While it isn’t as blatant in the OT, love is there, however.
What did Jesus say were the two greatest commandments?
36Master, which is the great commandment in the law?
37Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38This is the first and great commandment.
39And the second is like unto it, Thou shalt love thy neighbour as thyself.
Why did this answer satisfy Jesus’ critics (cf Lk 10:28)? Because it was nothing new! This was already known!
Perhaps you have a study Bible. Do you see any cross references? I do.
Even then, it was about relationship.
However any relationship has rules. Any group of people have mores. Any society has laws. God is building a family, but it is a family of billions of children. It requires rules of conduct in order to maintain the relationships and keep them healthy.
Then, what is meant by “the end of the Law”? Has the Law been done away, nullified or made void? No, Jesus said nothing would pass from the Law until all had been fulfilled, including the passing of the heavens and the earth. Well, the earth is still spinning and going around the sun, so that’s not been accomplished yet. So, it must mean something other than the Law is finished.
And, indeed, to what end is the Law? What is the purpose of the Law? Why, to bring us to Christ! It’s the relationship thing, come full circle. We start with love, from love we proceed to show love towards God and man by keeping the Law, but in the end we wind up with a relationship with Christ.
“End” or “telios” can mean “the end to which all things relate, the aim, purpose” (Strong’s G5056). Since the Law has not been done away, according to Jesus’ own words, it must mean “aim” or “purpose” or even “goal” (according to a HCSB footnote).
Violating the Law violates our relationship! Sin is serious stuff! That’s why we have to recognize what sin is, and we have to realize how much we need a Savior, and we need to ask God to grant us the power to resist sin and evil so that we can maintain our relationship with Him. Through God’s Holy Spirit, Jesus promises us the power to overcome.
So, what of the oft-stated opinion that Jesus came to teach us to love each other, and that that was something new? Frankly, it’s a misreading of what Jesus said.
What was new isn’t that we are to love one another, but rather we are to love one another the way He loves us! Our limited sinful sort of love just won’t do! No, we must love each other with a sacrificial love, even as He showed us how to do.
