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. (1 Corinthians 13:4-8a, ESV)
God defines love, but these verses describe it in great detail. Do you want to know if you are showing love? Then see if these attributes are evident in you. If you are not able to show these qualities in some degree, you do not love. This goes for your spouse as well as the people around you.
Prayer: Lord, thank you for showing me what love looks like.
