"And now these three remain: faith, hope and love. But the greatest of these is love." (1 Corinthians 13:13)
Why would love be the greatest of these you may ask? I believe it is because faith and hope depend on love to exist. Without love, how can you have true faith? Paul says, "If I have a faith that can move mountains, but do not have love, I am nothing." (1 Corinthians 13:2) And, how can you hope for something that you do not truly love? Wouldn't make any sense. Lastly, I believe love is the greatest of these simply because "God is love." (1 John 4:8) and there is no one greater than He!
So, with this knowledge, how should we live? We should "live" a life of love, in all things we do (big and small). We should love because God first loved us (1 John 4:19)! What kind of love should we love with? The most selfless kind. As Jesus said, “A new command I give you: Love one another. As I have loved you, so you must love one another." (John 13:34) In fact, love is in both of the greatest commandments that Jesus taught. 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 neighbor as yourself." (Matthew 22: 37-39)
I'd say Jesus is pretty clear on this subject.
How do you treat your neighbor? How do you treat your spouse? How do you treat "God"? Commit to no more arguing, no more bickering, no more selfishness, but rather, let your life be about the "love" that Jesus taught from this day forward.
No excuses, because remember how much God has loved "YOU":
"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."
