Love is not separate to God's law. Love is expressed through obedience to Gods' law which is why Jesus says on these two commandments of love to God and love to man hang all the law and the prophets *Matthew 22:36-40. Paul agrees with Jesus in Romans 13:8-10 when he says that we show our love to our fellow man by keeping those laws in Gods' commandments that show us our duty of love to our neighbor (Exodus 20:12-17). James also agrees with Jesus and Paul in James 2:8-12 when he says if we break anyone of Gods' 10 commandments we stand guilty before God of breaking all of them. While John also agrees in 1 John 5:2-3 that we need to be born of God to love and walk in His Spirit which is Gods' new covenant promise in all those who believe and follow what Gods' Word says *John 3:3-7; 1 John 3:6-9; Galatians 5:16; Hebrews 8:10-12 from Jeremiah 31:31-34 and Ezekiel 36:24-27. No one loves God therefore by breaking God's law and not believing and following what Gods' Word says. Those are the children of the devil according to 1 John 3:6-10.
Take Care
keeping a law is not the law of liberty, the law of freedom which Christ has made us fee from the law of sin and death.
We could and cannot be justified by law, justification only comes by believing in Christ being just and the justifier of those who do not believe in law...
Romans 3:25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.
28 Therefore we conclude that a man is justified by faith without the deeds of the law.
29 Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:
30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
31 Do we then make void the law through faith? God forbid: yea, we establish the law.
Being justified by faith, then the love of God is shed into our hearts, by the Holy Ghost given to us..
Romans 5: 1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
2 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.
3 And not only so, but we glory in tribulations also: knowing that tribulation worketh patience;
4 And patience, experience; and experience, hope:
5 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
