1 Corinthians 13:4-7 English Standard Version (ESV)
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.
This is the description of perfect love. It does not say anything about a measure of love. If we only love others who will return a measure of love, is that love?
Luke 6:34 English Standard Version (EV) And if you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners, to get back the same amount.
If we view love of money as an element of this verse then love is part of the equation. 1 Corinthians 13 does not speak to a measure of love because it is not to be withheld.
Matthew 22:37 English Standard Version (ESV) 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.”
Since the perfect love of God abides in us without measure we are asked not to love by measure.
What would you do for love?
Before you answer that remember that Christ died willingly to gain our love. He held nothing back.
