"Love is patient, love is kind. It does not envy, it does not boast. It is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails..." -1 Corinthians 13:4-8
God says that true love does not envy or boast. Are you constantly dissatisfied with what you have? Are you constantly bragging about yourself, without ever building other people up. If these things are true of you, then you do not love God or your "neighbor." God sees love as an action; not a feeling. So if you truly love your neighbor, you won't desire his things or place more importance on yourself than you do him; and if you truly love God, you will decide to be satisfied with what He has given you and you will never boast in yourself but only in the One who died for you.
So take some time today to think about who you are compared to who God is. When you do that, you will find it utterly impossible to see anything about yourself as worthy of boasting about.
