For this cause I bow my knees unto the Father of our Lord Jesus Christ, 15 Of whom the whole family in heaven and earth is named, 16 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; 17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, 18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height; 19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God. 20 Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, 21 Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.
Hebrews Ch 7 If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? 12 For the priesthood being changed, there is made of necessity a change also of the law 15 And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, 16 Who is made, not after the law of a carnal commandment, but after the power of an endless life. 17 For he testifieth, Thou art a priest for ever after the order of Melchisedec. 18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. 19 For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God. 20 And inasmuch as not without an oath he was made priest. 26 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; 27 Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself. 28 For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
Jesus Christ is a priest forever and created upon his Death a New Covenant with the Isrealites and the whole world. And as it says when there is a change of Priest there is a change of Law... John Chapter 13 Therefore, when he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him. 32If God be glorified in him, God shall also glorify him in himself, and shall straightway glorify him. 33Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you. 34A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. 35By this shall all men know that ye are my disciples, if ye have love one to another. Now we understand that the true law of Jesus is to Love onbe another. When Jesus said it is finished, the end was gained of being slave to Law. Now we live in the Spirit and Love!
So, therefore, if the law was changed by Jesus being a new Priest and a covenant that is forever, Then the New Covenant writes Love on our hearts as HOW to live. Live in love, do everything with Love, make Love your goal and use Love to get there
Hebrews Chapter 8 “Behold, the days are coming, declares the Lord, when I will establish a new covenant with the house of Israel and with the house of Judah, 9 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt. For they did not continue in my covenant, and so I showed no concern for them, declares the Lord. 10 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: Therefore if God has written the Law on our Heart, heart heart heart, then it is Love. I will put my laws into their minds, and write them on their hearts, and I will be their God, and they shall be my people.
The first Christians lived in harmony. I was thinking the other day about love, what is it, how do we feel about loving one another. St Paul describes it good enough, and I wondered, and thought, Love is Harmony, Love is when people drop walls and share themselves openly with one another. There creates a unity amongst them. Unity. Holy loving unity. A whole, there isn't any divisions amongst them. There is harmony where love is, as it says a house divided cannot stand, united we stand divided we fall. Love one another today in the Spirit of God.
Love – The Fulfilling of the Law "If the love of God is shed abroad in your heart," says Mr. Moody, "you will be able to fulfill the law." Paul reduces the commandments to one: "Thou shalt love," and says that "love is the fulfilling of the law." This truth is demonstrated thus: Principles Underlying the Ten Commandments 1. Love to god will admit no other God. Faith and loyalty. Heb. 11 :6; Matt. 4:8-10. 2. Love will not debase the object it adores. Worship. Jer. 10:10-12; Ps. 115:3-8; Rev. 14:6,7. 3. Love to God will never dishonor His name. Reverence. Ps. 111:9; 89:7; Heb. 12:28; 2Tim. 2:19. 4. Love to god will reverence His day. Holiness, or sanctification and consecration. I Peter 1: 15, 16; Heb. 12:14;Ex. 31:13; Eze. 20:12; 1 Cor. 1:30; Provo 3:6. 5. Love to parents will honor them. Obedience, or respect for authority. Eph. 6:1-3; Col. 3:20; 2 Kings 2:23,24. 6. Hate, not love, is a murderer. Love. Lev. 19:17; 1 John 3:15; Matt. 5:21-26;, 43-48. 7. Lust, not Love, commits adultery. Purity. Matt. 5:8; Eph. 5:3,4; Col. 3:5,6; 1 Tim. 5:22; 1 Peter 2:11. 8. Love will give, but never steal. Honesty. Rom. 12:17; Eph. 4:28; 2 Thess. 3:10-12. 9. Love will not slander nor lie. Truthfulness. Eph. 4:25; Col. 3:9; Prov. 6:16-19; 12:19; Rev. 21:27; 22:15. 10. Love's eye is not covetous. Contentment and unselfishness. Eph. 5:5; Col 3:5; 1 Tim. 6:6- 11; Heb. 13:5.
When we invite God into our hearts and our lives....He is the one who loves through us...for God is love and teaches us how to love one another too.
More modern than the hymns quoted by @Ken Anderson since it was written in 2016, but it seems to fit here.
