The Bible has something to say about every kind of love there is: God's love for us, and our love for Him, in marriages, families and between friends. Here are some of the best:
Love the LORD your God with all your heart and with all your soul and with all your strength.
A friend loves at all times, and a brother is born for a time of adversity.
Song of Songs 8:6-7
Place me like a seal over your heart,
like a seal on your arm;
for love is as strong as death,
its jealousy unyielding as the grave.
It burns like blazing fire,
like a mighty flame.
Many waters cannot quench love;
rivers cannot sweep it away.
If one were to give
all the wealth of one's house for love,
it would be utterly scorned.
Hearing that Jesus had silenced the Sadducees, the Pharisees got together. One of them, an expert in the law, tested him with this question: "Teacher, which is the greatest commandment in the Law?" Jesus replied: "'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment. And the second is like it: 'Love your neighbour as yourself.' All the Law and the Prophets hang on these two commandments."
"If you love those who love you, what credit is that to you? Even sinners love those who love them. And if you do good to those who are good to you, what credit is that to you? Even sinners do that. And if you lend to those from whom you expect repayment, what credit is that to you? Even sinners lend to sinners, expecting to be repaid in full. But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be children of the Most High, because he is kind to the ungrateful and wicked. Be merciful, just as your Father is merciful.
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
Let no debt remain outstanding, except the continuing debt to love one another, for whoever loves others has fulfilled the law.
1 Corinthians 13:4-7
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonour others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
Therefore, as God's chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity.
1 John 3:16-18
This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? Dear children, let us not love with words or speech but with actions and in truth.
