What is an overview of Christian spiritual practices for cultivating and increasing love over time?

Love is, without question, the most fundamental virtue and principle of Christianity. The Apostle John makes this very clear: > 7 Beloved, let us love one another, **for love is from God, and whoever loves has been born of God and knows God**. 8 **Anyone who does not love does not know God, because God is love**. [1 John 4:7-8, ESV] The Apostle Paul seconds this in 1 Corinthians 13: > If I speak in the tongues of men and of angels, **but have not love**, **I** > **am a noisy gong or a clanging cymbal**. 2 And if I have prophetic > powers, and understand all mysteries and all knowledge, and if I have > all faith, so as to remove mountains, **but have not love**, **I am nothing**. > 3 If I give away all I have, and if I deliver up my body to be > burned, **but have not love, I gain nothing**. > > 4 **Love is patient and kind; love does not envy or boast; it is not arrogant** 5 **or rude. It does not insist on its own way; it is not irritable or resentful;** 6 **it does not rejoice at wrongdoing, but rejoices with the truth.** 7 **Love bears all things, believes all things, hopes all things, endures all things.** > > 8 **Love never ends**. As for prophecies, they will pass away; as for > tongues, they will cease; as for knowledge, it will pass away. 9 For > we know in part and we prophesy in part, 10 but when the perfect > comes, the partial will pass away. 11 When I was a child, I spoke like > a child, I thought like a child, I reasoned like a child. When I > became a man, I gave up childish ways. 12 For now we see in a mirror > dimly, but then face to face. Now I know in part; then I shall know > fully, even as I have been fully known. > > 13 So now faith, hope, and love abide, these three; **but the greatest of these is love**. And how to forget Jesus' own words in Matthew 22: > 34 But when the Pharisees heard that he had silenced the Sadducees, they gathered together. 35 And one of them, a lawyer, asked him a question to test him. 36 “Teacher, which is the great commandment in the Law?” 37 And he said to him, **“You shall love the Lord your God with all your heart and with all your soul and with all your mind**. 38 This is the great and first commandment. 39 And a second is like it: **You shall love your neighbor as yourself**. 40 **On these two commandments depend all the Law and the Prophets**.” [Matthew 22:34-40, ESV] With love being such a fundamental and central core principle of Christianity, a question that one should naturally ask next is: *how to have this kind of love?* Is *love* (the Christian concept of *love*) a quality that can be cultivated, developed and increased over time? If so, *how*? Are there **concrete spiritual practices** that can increase a Christian's capacity to experience and express *love*? Assuming that different denominations might answer these questions differently, I'd rather play it safe by requesting an **overview** of spiritual practices.
