I am not a coffee drinker I never cared for the bitter coffee taste. To me coffee is sharp and bitter, however if you make it into a cappuccino with sugar and cream I really love that.
Sometimes loving people is like this. Some people don't make it easy to love them. Like coffee they are sharp and bitter. These people put a bitter taste in your mouth. However with God we can put on love like the sugar and cream in a cup of coffee.
Just like it takes sugar and cream for me to enjoy the coffee I must have the love of God and put on sweetness in order to love others as we are commanded to.
A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.
