True love

4 Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,

5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;

6 Rejoiceth not in iniquity, but rejoiceth in the truth;

7 Beareth all things, believeth all things, hopeth all things, endureth all things.

8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.

1 Corinthians 13:4-8

According to the previous verses, we can see that loving goes beyond our actions, it is something that is born from within us, you cannot say that you have love and have envy, boast, do the wrong thing, just think of yourself, irritate yourself with others, hold a grudge against others, etc.

How can we say that we love God and not love our neighbor? Well, as John says, how can we say that we love God whom we do not see and hate our brothers whom we do see? True love is shown by loving our neighbor, not seeking our own good but that of others. Remember that we have the greatest show of love on the cross, to Christ giving His life for sinners who deserved nothing good.
