God is love.
1 John 4:8 He that loveth not knoweth not God; for God is love.
1 John 4:16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
Jesus defines the ultimate love.
John 15:13 Greater love hath no man than this, that a man lay down his life for his friends.
Romans 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
1 John 4:10 Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
Those who believe the gospel and are baptised into Jesus Christ are commanded to emulate his love.
1 John 3:16 Hereby 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.
Paul describes the characteristics of love in his letter to the Corinthians
Corinthians 13:1 NKJV Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal. 2 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, but have not love, I am nothing. 3 And though I bestow all my goods to feed the poor, and though I give my body to be burned, but have not love, it profits me nothing.
4 Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; 5 does not behave rudely, does not seek its own, is not provoked, thinks no evil; 6 does not rejoice in iniquity, but rejoices in the truth; 7 bears all things, believes all things, hopes all things, endures all things.
8 Love never fails. But whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away. 9 For we know in part and we prophesy in part. 10 But when that which is perfect has come, then that which is in part will be done away. 11 When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. 12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known. 13 And now abide faith, hope, love, these three; but the greatest of these is love.
This love (Greek ‘agape’) does not require emotional attachment.
Christ commands us to love our enemies.
Matthew 5:43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. 44 But 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; 45 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. 46 For if ye love them which love you, what reward have ye? do not even the publicans the same? 47 And if ye salute your brethren only, what do ye more than others? do not even the publicans so? 48 Be ye therefore perfect, even as your Father which is in heaven is perfect.
1 Timothy 1:5 Now the end of the commandment is charity (love) out of a pure heart, and of a good conscience, and of faith unfeigned:
