If Christianity can be summarized in one word, it would be love. If the whole Bible can be summarized into one word, it would be LOVE.
You see, God is love. He Himself is love. It is not something He does, it is who He is.
1 John 4:8He that loveth not knoweth not God; for God is love.
And because God is love, love will NEVER fail.
1 Corinthians 13:8Charity [love] never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
It's because of Love that God sent His Son that anyone who believes in Him may not perish but have eternal life.
John 3:16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
The whole law can be summarized into two commandments - love the Lord your God with all your heart, all your soul, all your strength AND love your neighbour as yourself.
Matthew 22:37-40Jesus said unto him, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets."
1 John 3:23And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
Romans 13:8-10Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
Love is the distinguishing mark of a true disciple of Christ.
John 13:35By this shall all men know that ye are my disciples, if ye have love one to another.
Love is first in the list of the gifts of the Holy Spirit.
Galatians 5:22-23But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.
Love is the greatest; above both faith and hope.
1 Corinthians 13:13And now abideth faith, hope, charity, these three; but the greatest of these is charity.
Love is the only true remedy of fear.
1 John 4:18There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
2 Timothy 1:7For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
The glue that holds together kindness, mercy, patience, forgiveness, longsuffering, etc is Love.
Colossians 3:12-14Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering; Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye. And above all these things put on charity, which is the bond of perfectness.
Love even covers sins - not one or two, but a multitude of sins.
1 Peter 4:8And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins.
Proverbs 10:12Hatred stirreth up strifes: but love covereth all sins.
Love is way above ALL spiritual gifts. Spiritual gifts will end, love will never end.
1 Corinthians 13:1-3Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing.
1 Corinthians 13:8Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
And guess what, nothing can separate us from the love of Christ
Romans 8:35-39Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. Nay, in all these things we are more than conquerors through him that loved us. For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
So what should we as Christians do?
We should Love one another
John 13:34A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
Hebrews 13:1Let brotherly love continue.
1 John 4:7Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
1 John 4:20-21If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? And this commandment have we from him, That he who loveth God love his brother also.
1 Thessalonians 4:9But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.
Galatians 5:13For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
Love demands actions. Words only are not enough.
1 John 3:18My little children, let us not love in word, neither in tongue; but in deed and in truth.
Love demands we lay down our lives for the brethren.
1 John 3:16-17Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren. But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?
Husbands, love your wives.
Ephesians 5:25Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
Ephesians 5:33Nevertheless let every one of you in particular so love his wife even as himself; and the wife see that she reverence her husband.
Colossians 3:19Husbands, love your wives, and be not bitter against them.
We should love our enemies.
Luke 6:35But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
Matthew 5:44-48But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the publicans so? Be ye therefore perfect, even as your Father which is in heaven is perfect.
2 Kings 6:21-23And the king of Israel said unto Elisha, when he saw them, My father, shall I smite them? shall I smite them? And he answered, Thou shalt not smite them: wouldest thou smite those whom thou hast taken captive with thy sword and with thy bow? set bread and water before them, that they may eat and drink, and go to their master. And he prepared great provision for them: and when they had eaten and drunk, he sent them away, and they went to their master. So the bands of Syria came no more into the land of Israel.
Loving Jesus is obeying Him.
John 14:15If ye love me, keep my commandments.
John 14:21He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
If the Bible places so much emphasis on love, how can we as Christians think we don't need it anymore? How can we be light and salt in this world without love - first for God and also for one another?
In light of this revelation on love, read the whole of 1 John. That's the book on love.
